According to some configurations of this teaching, with reference to FIG. 1 here, a surgical system 10 for performing a surgical procedure is shown. The system 10 may also be used for other medical procedures such as endoscopic procedures. In general, the surgical system 10 can include, but is not limited to, the user interface 12A and the surgical robot 16. Robot 16 can include at least one controllable element that can be used to perform surgery on patient 18. Such elements may be introduced into the anatomical features or cavities of patient 18 to perform surgery on surgical targets, or may help position other parts of robot 16 for surgery. good. The user interface 12A can communicate with the robot 16 to control and receive feedback and / or data from the robot 16. A plurality of displays and user input devices can be included in the user interface 12A. Similarly, a plurality of robots 16 may be included in the surgical system 10. Multiple displays and / or user input devices are desirable, for example, for teaching / educational purposes, or for scenarios where the robot 16 contains more controllable elements than can be easily controlled by a single doctor. possible.

Continuing with reference to FIG. 1, the user interface 12A can display an image that is captured and relayed from the imaging or visual system 13 to the user interface 12A. The imaging system 13 may be part of the robot 16 or may be introduced into the robot 16 during surgery. The imaging / visual system 13 may be controlled by the robot 16. In the alternative configuration, the imaging / visual system 13 may be an optional auxiliary component 20 that may not be directly controlled by the robot 16. The image displayed in the user interface 12A can provide a field of view of the surgical site that allows the surgeon 22 to control the robot 16 with visual feedback. The user interface 12A can include any of various displays such as monitors, touch screens, tablets, or equivalents. In configurations where the user interface 12A is capable of receiving user input (eg, a touch screen), a user such as the surgeon 22 pans, zooms, or otherwise pans the field of view shown on the display of the user interface 12A. It may interact with the user interface 12A to operate. In addition, other display functionality (eg, taking a picture, recording a video, controlling the robot 16) may also be commanded through the user interface 12A.

Continuing with reference to FIG. 1, the surgeon 22 can interact with the user interface 12A to control the movement of the robot 16. In an exemplary configuration, the user interface 12A can move a controllable element (eg, an arm or surgical tool) of the robot 16 around and / or along with various degrees of freedom during the surgical procedure. .. The user interface 12A may have a plurality of parts that can be independently controlled by different parts of the body of the surgeon 22 (eg, right hand, left hand, right foot, left foot, etc.). In addition, the user interface 12A may have different parts or parts of the robot 16 that can control functionality. If the user interface 12A does not include a touch screen, the user interface 12A may include one or more structures that can be displaced by the surgeon 22 to provide input commands to the robot 16. These structures can vary from configuration to configuration and any suitable type of interface may be used. In some configurations, one or more joysticks, triggers, scroll wheels, balls, etc. may be displaced by the surgeon 22 to control the robot 16. In an alternative configuration, the user interface 12A may mimic the working edge of the surgical tool used in the procedure. This may allow the surgeon 22 to operate the surgical tool as if performing an open surgery. Still in other configurations, the user interface 12A can be an exoskeleton. In such a configuration, the user interface 12A can be worn by the surgeon 22 and inputs can be provided to the user interface 12A as the surgeon 22's body moves.

Continuing with reference to FIG. 1, in various configurations, the user interface 12A can provide feedback, such as tactile feedback, to the surgeon 22. The feedback may be force feedback capable of making the effort required to displace a portion of the user interface 12A in proportion to the amount of force exerted through the drive system of the robot 16. However, it is not limited to that. Vibration feedback or other tactile feedback may also be utilized. Auxiliary components 20 can optionally be included in or interface with the surgical system 10. Auxiliary components 20 can include, but are not limited to, a visual or imaging system 13, such as an endoscope, an irrigation or blowing system, a lighting system, and / or a suction system. APIs may be provided to facilitate the interface between the components of the surgical system 10 and the auxiliary components 20. Any component described herein as an auxiliary component 20 may be included as part of the robot 16 in an alternative configuration and vice versa. The at least one controller 15 may also be included as part of the surgical system 10. The at least one controller 15 analyzes user inputs to the user interface 12A and generates commands for the robot 16 based on these inputs, to the data received from the lighting / visual system 13. It may perform some functions such as image processing based on the image and controlling the delivery of feedback to a user such as a doctor 22.

Still further referring to FIG. 1, the barrier 24 can isolate a portion of the surgical system 10 from the rest of the surgical system 10. In some configurations, the barrier 24 separates the single-use or multi-use disposable component of the robot 16 from the durable component of the robot 16, which may not be intended for periodic disposal. May be. The barrier 24 may be, for example, a sterile barrier capable of separating the sterile portion of the surgical system 10 from the sterile portion of the surgical system 10 to create a sterile field. In some configurations, the barrier 24 can be a sterile barrier that can isolate the sterile portion of the robot 16 and the patient 18 from other components of the surgical system 10. In configurations with disposable items, the disposable item may be a sterile portion of the surgical system 10 that can be isolated from other parts of the surgical system 10 by the barrier 24. In the representation embodiment shown in FIG. 1, the barrier 24 is depicted with a line break. This is because the aseptic barrier 24 will generally have a portion of the robot 16 as well as the patient 18 on the aseptic side, while the barrier 24, depending on the configuration, is a different component of the surgical system 10. It is done to indicate that it can be surrounded, covered, or otherwise isolated from the sterile field.

Referring now to FIG. 2, the user interface 12A (FIG. 1) can be physically and electrically remote from each other, but is not limited to, and among several methods, through network 21. It may include, but is not limited to, a display 12 and a user input device 14 that may be interfaced. In addition, the illumination / vision 13 can be integral with the robot 16 and can cross the barrier 24 to illuminate the surgery of the patient 18 for the doctor 22. Auxiliary components 20 can optionally be included in system 110.

Primarily with reference to FIG. 3, the surgical robot 16 may be incorporated into the surgical system 10 (FIG. 1). The surgical robot 16 can include a base 30 that can support other components of the robot 16. In addition, in some configurations, the base 30 may act as a cart that can allow the surgical team to steer the robot 16 to the desired position. The cart may be an electric cart that can be driven to a desired location, or it may be a non-electric cart that can be manually moved. The base 30 may also include electronic components of the robot 16 such as a processor or controller 15, memory components, power components and the like. The robot 16 can also include a drive component 34 that can drive the operation of the manipulator 36. The drive component 34 may include various motors for driving the manipulator 36, hydraulic components, and couplings. The manipulator 36 can control the operation of the component 38 to be operated, which may be installed in the manipulator 36. The operated component 38 may include a articulated shaft or lumen (not shown) that can direct a surgical tool or device attached to or extending through it. Possible surgical tools are described in an endoscope, eg, US Patent Publication No. 2014/0221749, filed January 31, 2014, entitled Endoscope with Panable Camera. Endoscopes can be included. Other surgical tools include imaging devices, cutting tools (eg shavers), retractors, grippers, ablator, lighting sources, electrocautery devices, staplers, suture tools, milling cutters, drilling tools, rotary cutters, irrigation system outlets, etc. And / or may include, but is not limited to, blow system outlets. For illustration purposes, three operated components 38 are shown. Any number of manipulated components 38 may be controlled by the manipulator 36. A plurality of manipulators 36 may be driven by a single drive component 34. A plurality of drive components 34 may also be included to drive at least one manipulator 36.

Primarily continuing with reference to FIG. 3, the arm 32 optionally includes several fittings that can be positioned by the user and allow rotational or translational motion of the various compartments of the arm 32. But it may be. Such fittings can allow the arm 32 to position the manipulator 36 in the proper position for the surgical procedure. In some configurations, the base 30 can support the robot 16 against falls when the arm 32 is fully extended. The arm 32 may include an actuator that may be manually moved into place or controlled to drive the arm 32 to a desired location. In various configurations, the arm 32 is, for example, at least one wiring such as, but not limited to, transmitting power, data, hydraulic power, fluid, and / or light between the base 30 and the driven component 34. 19 may be included. The at least one wire 19 may also be an optical fiber line that, in some configurations, can be used for data transmission or light transmission. At least one wire 19 is configured with power, data / commands, forces, fluid (eg, irrigation fluid or blown gas), and / or light driven from the base 30 or another part of the surgical system 10 (FIG. 1). It can be made possible to communicate with the element 34. Electric power, data, hydraulic power, fluid, lighting and the like can be controlled by, for example, but not limited to, a user input device 14 (FIG. 1).

Continuing with reference to FIG. 3, with respect to hydraulic power, in some configurations, the base 30 may include a master cylinder and a motor that drive the hydraulic fluid through at least one wire 19. For fiber optics, light can be transmitted through at least one wire 19 and can cross the barrier 24 into the manipulator 36 for use in various ways. The inclusion of at least one fiber optic line may also allow the transmission of data. With respect to the data, for example, a sensor in the drive component 34 may collect the data and transmit it to the controller 15 in the base 30 via at least one wire 19. In addition, or as an alternative, a sensor located within the manipulator 36 and the operated component 38 collects data and transmits it to at least one wire 19 through the barrier 24 for processing within the base 30. be able to. In another embodiment, with respect to thermal management, at least one wiring 19 accommodates a liquid and / or gas between the base 30 and the drive component 34, for example by heat conduction to cool the drive component 34. Can be configured as At least one wire 19 can conduct water / gas for blowing and irrigation. At least one wire 19 can be used for suction and / or removal of fluid or residue from the surgical site. The controller 15 can control at least one wire 19 to provide, for example, the services outlined here.

Still further, with reference primarily to FIG. 3, the barrier 24 can act as a sterile barrier, isolating the manipulator 36 and the operated component 38 from the rest of the robot 16. In some configurations, a portion of the barrier 24 can be retained or trapped between the drive component 34 and the manipulator 36. Force may be transmitted to the manipulator 36 through this portion of the barrier 24 so as to drive the manipulator 36. The portion of the barrier 24 retained between the drive component 34 and the manipulator 36 can be a solid and continuous portion of the barrier 24. That is, the portion of the barrier 24 between the drive component 34 and the manipulator 36 may not include voids, orifices, openings, holes, passages, or other such interruptions. The integrity of the barrier 24 can be maintained as the force is transmitted through it. The manipulator 36 may confine the barrier 24 between the two while setting the robot 16 and hook it onto the drive component 34. The manipulator 36 and the component 38 to be operated may be supplied as a single-use or multiple-use disposable item. The component 38 to be operated may be pre-installed or pre-assembled in the manipulator 36. These parts of the surgical system 10 (FIG. 1) may be provided in a sterile package. The manipulator 36 and the operated component 38 may be installed in the system 10 (FIG. 1) prior to surgery.

Referring now to FIG. 4A, the articulated compartment 40 is a shaft, a spliced or otherwise articulated shaft, some nested shafts, some vertebral-like members or other pivot / hinge connections. It may include, but is not limited to, a member, a ball and socket member, and / or any combination of one or a series of living hinges. The operated component 38 may be hollow or may include at least one lumen (not shown) and may pass through the trocar 37. The lumen (or some lumen) may serve as a pathway through which the surgical tool 52 can be introduced to the surgical site. Lumens may also be used to facilitate blowing, irrigation, irradiation, etc. of the surgical site. The utility component 54 operably connected to the operated component 38 may be a mechanical control, light transmission, information transmission, fluid transmission, and power transmission component. The utility component 54 may extend through a lumen (not shown) shared with one or more other utility components 54, or each may have its own lumen. .. There may be various different utility components 54 housed within the operated component 38. Light transmission components may include, for example, fiber optic bundles, ribbons, optical pipes, light projection elements, and / or equivalents. The information transmission component may include, for example, a bundle of electrical cables or a ribbon. Such a cable or bundle may be connected to a surgical tool 52 having an imaging device located at the end of the operated component 38. Such cables may also be used to transmit power to the surgical tool 52. The fluid transmission component may provide a path for the fluid (eg, blown gas or irrigation fluid) to be introduced into the patient's anatomy.

Still primarily with reference to FIG. 4A, the operated component 38 can include a joint movement type compartment, compartment, or region 40 that can be connected to the variable portion 39 of the operated component 38. The variable portion 39 can extend into the manipulator 36 and can also extend through the trocar 37 to facilitate introduction into the patient. The variable portion 39 can be, for example, but not limited to, flexible, articulated, or non-flexible. The component 38 to be operated may be preassembled on the manipulator 36. Similarly, the operated component 38 may be preassembled with a utility component 54 already located therein. As mentioned above, these may be provided in a sterile package. In configurations where at least one or part of the utility component 54 is not pre-installed in the manipulator 36 or the operated component 38, the utility component 54 or part of the utility component 54 is similarly packaged. May be done. Utility component 54 can be, but is not limited to, a mechanical control component or actuator. The actuator can extend into the operated component 38 and along its length. In addition, the actuator can extend into the manipulator 36 through a gap or opening in the variable portion 39.

Here, mainly referring to FIG. 4B, any suitable number of actuators 54A, 54B, 54C may be included in the various configurations. The number of actuators 54A, 54B, 54C may be determined, at least in part, by the number of individually operable components or features within the operated component 38. In some configurations, the first actuator 54A, the second actuator 54B, and the third actuator 54C are shown and depicted as wires for simplicity. In some configurations, the actuators 54A, 54B, 54C may be a push rod or any other suitable material. Multiple different types of actuators may also be used within the same configuration. For example, some manipulated components 38 actuate some features with tension wires and use actuators that can exert both pulling and pushing power to achieve the actuation. It may be activated. One or more actuators 54A, 54B, 54C may be associated with the surgical tool 52. In the exemplary configuration shown in FIG. 4B, driving the second actuator 54B may actuate the surgical tool 52 or the end effector included as part of the surgical tool 52. This is represented expressively by a surgical tool 52 that changes shape (relative to FIG. 4A) in response to displacement of the second actuator 54B.

Referring here to FIG. 4C, the first actuator 54A, the second actuator 54B, and the third actuator 54C may be driven to actuate certain features of the component 38 to be operated. Such operations include, for example, opening or closing a jaw or clamp on the surgical tool 52 (see FIG. 4B), panning of the imaging device, camera, and / or lighting system included in the surgical tool 52, deployment of a retractor, and the like. May cause. The actuator of one or more of the first actuator 54A, the second actuator 54B, and / or the third actuator 54C is one or more joint moving parts or joints in the joint movement type compartment 40. It may be driven so as to cause displacement of the joint movement type compartment 40 around 51. In response to the displacement of the first actuator 54A and the third actuator 54C in the exemplary configuration, the articulated compartment 40 will be oriented with the articulated compartment representation 56A of the dotted contour. Controlling the articulated compartment 40 via mechanical control components makes it possible to minimize surgical invasiveness. In some cases, such joint movements may allow surgery to be performed through only a single incision in the patient.

Here, with reference to FIG. 4D, the manipulated component 38 may each have a plurality of regions or compartments that can be articulated to varying degrees. For example, the operated component 38 may consist of a variable compartment 39 and a joint movement type compartment 40A. The joint movement type compartment 40A may be only a small part of the operated component 38. Alternatively, the operated component 38 may include several articulated compartments 40A that can be interspersed by intervening in the variable compartment 39. In such a configuration, each articulated compartment 40A can be articulated to different degrees. Each region of the component 38 to be manipulated may or may not be independently controllable. The joint movement type compartment 40A can also include a gradual stage of joint movement within the joint movement type compartment 40A. That is, one or more of the joint movement type compartments 40A may be jointed or spliced more closely than the other compartments. Alternatively, the density of the articulated joints or joints may gradually increase or decrease along the length of the articulated compartment 40A. The operated component 38 can include at least one first joint movement type subdivision 41 and at least one second joint movement type subdivision 42. The second joint movement type subdivision 42 may be a distal joint movement type subdivision, and the first joint movement type subdivision 41 may be a proximal joint movement type subdivision. The second joint movement type subsection 42 can be jointly operated more closely than the other divisions of the joint movement type compartment 40A, for example, but is not limited to, and precise control of the surgical tool 52 when performing surgery. Can be made possible. In a configuration in which the second articulated subdivision 42 is articulated more closely than the rest of the operated component 38, the second articulated subdivision 42 has fine movement and control during surgery. May be used to do most. One or more actuators 54A, 54B, 54C, 54D, 54E may be used to control the first articulated subsection 41, and one or more actuators 54A, 54B, 54C. , 54D, 54E may be used to control the second joint motion type subsection 42. For example, the first actuator 54A and the fifth actuator 54E can be used to control the second joint movement type subsection 42, while the second actuator 54B and the fourth actuator 54D. , Can be used to control the first joint motion type subdivision 41. The remaining third actuator 54C may control the surgical tool 52. In the exemplary configuration, the first actuator 54A and the fifth actuator 54E are displaced. Orientation 56B is shown for illustration purposes to indicate the location of the second articulated subsection 42 as a result of this operation.

Referring now to FIG. 4E, the second joint motion subsection 42 is displaced as a result of any joint motion of the first joint motion subsection 41 or any other compartment of the joint motion compartment 40A. May be good. Any one of at least one first joint movement type subsection 41 may be controlled to position the surgical tool 52 and the second joint movement type subsection 42 more macroscopically. The operated component 38 can include several actuators 54A, 54B, 54C, 54D, 54E that cause some joint movement of the operated component 38 when driven. Additional actuators 54A, 54B, 54C, 54D, 54E can be used to more complexly articulate the manipulator 38 and the attached surgical tool 52. Actuators 54A, 54B, 54C, 54D, 54E are arranged to control the articulated compartment 40A of FIG. 4E, as described above in connection with FIG. 4D. In the exemplary configuration, the actuators 54B and 54D that control the first joint movement type subsection 41 are activated. Orientation 56C is shown for illustrative purposes to indicate the location of the articulated compartment 40A as a result of this operation.

Here, primarily with reference to FIG. 5, the articulated compartment or section 40B may be constructed in several different ways. In some configurations, the articulated compartment 40B may incorporate one or more living hinges 300 that may be actuated to articulate the articulated compartment 40B to the desired configuration or orientation. The living hinge 300 of the articulated compartment 40B may be straddled between several intermediary bodies 302. The mediation body 302 may be rigid for non-limiting embodiments and may provide either one or more mooring points 80 for one or more actuators 54 (FIG. 4A). Some of the intermediary bodies 302 may instead include passages 304A, 304B or plurality of passages 304A, 304B through which the actuator (eg, see 54A in FIG. 4B) may extend. Applying force through the actuator (eg, see 54A in FIG. 4B) can bend one or more of the living hinges 300 (eg, depending on the mooring point 80 of the actuator). .. By selectively exerting a force through an actuator (eg, see 54A in FIG. 4B), the articulated compartment 40B may be bent in the desired orientation as a result. Such a stack of living hinges 300 may be used to form part or all of the articulated compartment 40B. Depending on the configuration, the articulated compartment 40B is constructed from a stack of living hinges 300, which can be manufactured as a single component. The part may be a molded part in some configurations. Alternatively, the part may be machined or printed using a material addition process such as 3D printing. The intermediary body 302 can be, for example, but not limited to, a disk-like member. Although only three living hinges 300 are shown, any suitable number of living hinges 300 and mediation body 302 may be included to create the articulated compartment 40B of the desired length.

Primarily continuing with reference to FIG. 5, each intervention body 302 of the articulated compartment 40B can include a first passage 304A and a second passage 304B. The first passage 304A and the second passage 304B of adjacent mediation bodies 302 may be substantially axially aligned with each other. Each actuator for the articulated compartment 40B (see, eg, 54A in FIG. 4B) may be moored into the mooring point 80. In the exemplary configuration of FIG. 5, the mooring point 80 is shown in the termination mediation body 302A. The actuator 54 (see, eg, 54A in FIG. 4B) may be moored in an intermediary body 302 other than the terminal intermediary body 302A for series, depending on the configuration. As described above, when the force is exerted by one or more actuators in a coordinated fashion (eg, see 54A in FIG. 4B), the articulated compartment 40B may flex in the desired fashion. .. In some configurations, the series of living hinges 300 and mediation body 302 may be covered by a tube, sheath, or flexible sleeve 50 (FIG. 4A) when the articulated compartment 40B is fully assembled. ..

Here, with reference to FIG. 6, another configuration of the articulated compartment 40C with the mediation body 302 including the first living hinge 300A, the second living hinge 300B, and the passage 304 is shown. Similarly, as shown in FIG. 5, the terminal mediation body 302A of the articulated compartment 40C includes a mooring point 80 for the actuator (eg, see 54A in FIG. 4B). The first living hinge 300A can be angle offset with respect to the second living hinge 300B. For non-limiting embodiments, the first and second living hinges 300A, 300B may be positioned perpendicular to or substantially at right angles to any directly adjacent living hinges 300A, 300B. The first living hinge 300A can bend the joint movement type compartment 40C in the first plane (eg, up and down), and the second living hinge 300B can bend the joint movement type compartment 40C in the second plane (eg, left and right). In), the joint movement type compartment 40C can be flexed. Each of the mediation bodies 302 can include, for example, but not limited to, four passages 304. Each passage 304 can extend through either the first living hinge 300A or the second living hinge 300B. Actuators (eg, see 54A in FIG. 4B) may be grouped together in a collaborative set that can be operated to flex the articulated compartment 40C in a set of directions. For example, an actuator extending through passages 304 arranged oppositely to each other (eg, see 54A in FIG. 4B) may be interlocked to allow coordinated flexion of the articulated section 40C in a plane. .. By operating a set of interlocking actuators (eg, 54A in FIG. 4B) in conjunction with each other, the articulated compartment 40C may be positioned in a wider range of orientations than the articulated compartment 40B (FIG. 5). good.

In the configuration including the joint motion type compartment 40C with a plurality of joint motion type subdivisions, the first joint motion type subdivision 41 (FIG. 4D) can be flexed in the same plane or all in the same plane. May include some first living hinges 300A. The second joint movement type subsection 42 (FIG. 4D) is consistent with each other, but the angle with respect to the first living hinge 300A (FIG. 5) in the first joint movement type subsection 41 (FIG. 4D). It may include some second living hinges 300B (eg, at right angles).

Here, with reference to FIG. 7, an articulated compartment 40D in which the living hinge 300C is separated by an intermediary body 302 is shown. The living hinge 300C can be, for example, but not limited to, a cylinder or a cylindrical body, and can be made, for example, but not limited to, a flexible material. The living hinge 300C can be bent in any direction using substantially the same force. If desired, the living hinge 300C can be given an elliptical cross-sectional shape or any other cross-sectional shape. Having an asymmetric cross-sectional shape can allow the living hinge 300C to bend more freely in the first set of planes as compared to the second set of planes. The intermediary body 302 can be, for example, but not limited to, a disk-like. Each mediation body 302 can include several, for example, four passages 304. In some configurations, the intermediary body 302 does not need to include the four passages 304. Alternatively, the intermediary body 302 can include three passages 304. The number of passages 302 included may depend on the number of actuators (eg, see 54A in FIG. 4B) that will be included for the articulated compartment 40D. The actuator (eg, see 54A in FIG. 4B) can extend through the passage 304 and, for example, can be moored into, but not limited to, the mooring point 80 of the termination mediation body 302A. Actuators (eg, see 54A in FIG. 4B) may be grouped together in a collaborative set that can be used alone or together to bend the articulated compartment 40D to the desired orientation. Actuators (eg, see 54A in FIG. 4B) may extend through each set of passages 304 and be operated in concert with each other to bend the articulated compartment 40D in the desired orientation. ..

Again, primarily with reference to FIG. 4A, the various articulated compartments 40 to be joined may also be used. Such configurations can incorporate one or several fitting members that are interconnected to act as a set of kinematic pairs. These joint members may be acted upon to displace the articulated compartment 40 to the desired configuration or orientation. Applying force through an actuator included in the articulated compartment 40 (eg, see 54A in FIG. 4B) causes one or more joint members in the articulated compartment 40 to move relative to each other. Can be done. The number of fitting members to be displaced may depend on the mooring point 80 (FIG. 5) of the actuator (eg, see 54A in FIG. 4B) and the type of fitting involved. By selectively exerting a force via an actuator (eg, see 54A in FIG. 4B), the articulated compartment 40 may be bent in the desired orientation as a result.

Here, with reference to FIG. 8, a articulated compartment 40E constructed of several joint members 310 that are kinematically connected is shown. The fitting member 310 can be a ball and socket type fitting with respect to a non-limiting embodiment. Any other variety or combination of fitting types may be used in other configurations. The illustrated articulated compartment 40E includes four joint members 310. Any number of joint members 310 may be included to create the articulated compartment 40E of the desired length. Each joint member 310 may include a ball 312 and a socket 314. The ball 312 can be sized to fit and retain in the socket 314 of the adjacent joint member 310. The joint member 310 can also include a flange 316, which may include several passages 304. The alternative configuration may not include the flange 316, but may include any type of protrusion within which the passage 304 may be located. Such protrusions may be displaced in the radial direction.

Here, referring to FIG. 9, an assembly drawing of the joint movement type compartment 40F is shown. Some actuators 54A, 54B, 54C may extend, for example, through a passage 304 in the joint member 310. The first actuator 54A, the second actuator 54B, and the third actuator 54C may each be moored into the mooring point 80 in one of the joint members 310. In the exemplary configuration, the actuators 54A, 54B, 54C are moored into the mooring point 80 within the end joint member 310A. In some configurations, the actuators 54A, 54B, 54C may be wires. Actuators 54A, 54B, 54C may be operated in coordination with each other so that the articulated compartment 40E has the desired orientation. The joint movement type compartment 40E is shown in the working position. The second actuator 54B and the third actuator 54C are fed out, while the first actuator 54A is retracted to bend the articulated compartment 40E.

Referring now to FIG. 9A, the articulated section 40E may include a joint member 310 aligned such that the ball 312 of the subsequent joint member 310 and the joint of the socket 314 coalesce when assembled. .. The joint member 310 can be configured to have a channel 311 that can extend from the socket 314 of the joint member 310 to the ball 312. When the articulated compartment 40E is assembled, the channels 311 within each joint member can align with each other and provide a continuous path through the articulated compartment 40E. In some configurations, channel 311 can be configured to receive at least a portion of the surgical tool 52 (FIG. 4A) or auxiliary component 20 (FIG. 1) used during the surgical procedure. The portion accepted within channel 311 may be substantially flexible or flexible, but is not limited to that, and passively flexes as the articulated compartment 40E is articulated. May be done. A portion of the surgical tool 52 (FIG. 4A) or auxiliary component 20 (FIG. 1) received in channel 311 can move relative to the movement of the fitting member 310. For example, even if the surgical tool 52 (FIG. 4A) or part of the auxiliary component 20 rotates with respect to the joint member 310 when a force is applied to it via the rotational drive component 34C (FIG. 69). good. In addition, the surgical tool 52 (FIG. 4B) or auxiliary component 20 (FIG. 1) may be actuated or controlled via the associated actuator 54B (FIG. 4B). For example, displacement of one or more actuators 54B (FIG. 4B) may open and / or close the jaws of the surgical gripper. In some configurations, channel 311 may contain a flexible cannula or tube configured to receive at least a portion of surgical tool 52 (FIG. 4A) or auxiliary component 20 (FIG. 1). ..

Here, referring to FIG. 9B, a cross section of the joint motion type division 40E is depicted. A channel 311 extending from the socket 314 of each joint member 310 of the articulated compartment 40E to the ball 312 is shown. In some configurations, more than one channel 311 may be included in each joint member 310 of the articulated section 40E. The surgical tool 52 may be inserted through the pathway created by channel 311 so that the tool 52 is introduced to the surgical site. Alternatively, the surgical tool 52 or part of the auxiliary component 20 (FIG. 1) may be present in the pathway created by channel 311.

Here, primarily with reference to FIG. 10, the articulated compartment 40K can include an extension structure 330 with a first lumen 332A and a second lumen 332B. The elongated structure 330 may have, for example, a substantially square or rectangular cross section, but may have any other cross-sectional shape (eg, circular, hexagonal, octagonal). The articulated compartment 40K may be, for example, but not limited to, a single component (eg, extrusion). In various configurations, the articulated compartment 40K may be, for example, but not limited to nylon or a similarly flexible material. The second lumen 332B and the first lumen 332A can have a plurality of different diameters. The first lumen 332A can act as an actuator guide path through which the individual actuator 54 (FIG. 3A) can extend. The actuator (eg, see 54A in FIG. 4B) may be, for example,, but is not limited to, a wire or a cable. The second lumen 332B may have a diameter larger than, for example, the first lumen 332A. The second lumen 332B may be used to introduce one or more surgical tools up to the articulated compartment 40K or the operated component 38 (FIG. 3A). The second lumen 332B may be centrally located, while the first lumen 332A may be peripherally located.

Still referring to FIG. 10, the articulated compartment 40K can include a living hinge 335. The living hinge 335 can be produced by various cutouts 337. This arrangement can allow the extension structure 330 to bend about the living hinge 335 when the actuator attached to the portion of the extension structure 330 (see, eg, 54A in FIG. 4B) is displaced. .. The cutout 337 can include a set of holes 334L, 334R that can be placed on the facing surface of the extension structure 330. The set of holes 334L and 334R can include a left hole 334L and a right hole 334R located on the side of the inner partition forming the living hinge 335. Each living hinge 335 may be continuous with the rest of the extension structure 330. In a configuration in which the elongated structure 330 is circular in cross section, each hole in the set of holes 334L, 334R may be arranged 180 ° from each other. The left hole 334L and the right hole 334R may be, for example, but not limited to, angle offset from each other by 20-50 °. The left hole 334L and the right hole 334R can be circular or any other shape. The size and / or spacing of the left hole 334L and the right hole 334R can vary, but in an exemplary configuration, the holes 334L and 334R are depicted as having uniform size and spacing. In some configurations, the first surface 339A, the second surface 339B, the third surface (not shown), and the fourth surface (not shown) may include holes. The holes may be arranged in an alternating relationship if desired. For example, every other set of holes 334L and 334R may be, for example, but not limited to, angle offset by 90 ° from each other. In an exemplary configuration, every other set of holes 334L, 334R may be on the first surface 339A and the opposing third side surface (not shown), while the intervening set of holes is. , Will be on a fourth surface (not shown) opposite the second side surface 339B and the second surface 339B. Other sequences are possible. For example, every two or three sets of holes 334L and 334R can be angle offset from each other. Other shapes of the elongated structure 330 may provide additional possibilities. For example, the hexagonal shape may allow a set of holes 334L, 334R to alternate around three pairs of facing surfaces.

Still further with reference to FIG. 10, the cutout 337 can include several channels 336. Each channel 336 may be associated with a set of holes 334L, 334R. Each channel 336 can be continuous, for example, with, but not limited to, at least one of the left hole 334L and the right hole 334R. Each channel may extend from either the left hole 334L or the right hole 334R to an axially aligned hole on the facing surface of the extension structure 330. In an exemplary configuration, channel 336 is axially aligned left hole 334L or right hole 334R on a third surface (not shown) of extension structure 330 from one of right hole 334R or left hole 334L. Can be extended to. The spacing of the channels 336, the relationship between the channels 336 and the set of holes 334L, 334R, and the relationship between the channels 336 and the faces can vary in different configurations. The set of holes 334L, 334R and the arrangement of channels 336 (and thus the living hinge 335) can be selected to provide the ability to bend the elongated structure 330 in the desired orientation. Channel 336 can also serve as a stop. The width of the channel 336 can be adjusted to increase or decrease the range of motion. As the width is reduced, the permissible range of motion can also be reduced. Therefore, the point at which the stop will be encountered can be controlled by the width of the channel 336.

Continuing with reference to FIG. 10, channel 336 can also include features that can act as interlocks and create barriers or obstacles that can prevent torsional distortion during operation. Specifically, the geometric features 338A, 338B, 338C may require that the rotation of the elongated structure 330 about a major axis be accompanied by a translation about that axis. Geometric features 338A, 338B, 338C effectively lock the articulated compartment 40K in a certain orientation when the torsional force is applied, as the torsional force generally does not favor translational displacement. You may. Geometric features 338A, 338B, 338C can include protrusions or ridges 342 that can be received by the receptive recess 343. In an exemplary configuration, the ridge 342 can extend from the first wall of the channel 336, while the receptive recess 343 can be recessed into the facing surface of the channel 336. The morphology of the geometric features 338A, 338B, 338C may differ in other configurations.

Referring now to FIG. 11, the articulated compartment 40L can include a first lumen 332A and a second lumen 332B that can extend along the length of the elongated structure 330B. The extension structure 330B can include holes 334BL, 334BR, and channels 336B that can create a living hinge 335B. When the actuator (eg, 54A in FIG. 4B) that may be moored to the extension structure 330B is displaced in a controlled manner, the extension structure 330B can bend in a desired orientation about the living hinge 335B. .. Geometric features 338D within channel 336B can be wavy or toothed, but are not limited to. Each wave 344 can mutually lock the section of the extension structure 330B. Such an arrangement helps ensure that one or more of the geometric features 338D are engaged, regardless of the orientation of the elongated structure 330B.

Referring now to FIG. 12, the articulated compartment 40M can include a first lumen 332B and a second lumen 332A that can extend along the length of the elongated structure 330C. The extension structure 330C can include holes 334CL, 334CR, and channels 336C that can create a living hinge 335C. When the actuator (eg, 54A in FIG. 4B) that may be moored to the extension structure 330C is displaced in a controlled manner, the extension structure 330C can bend in the desired orientation about the living hinge 335C. .. The channel 336C can be formed so as to interconnect the sections of the elongated structure 330C. Channel 336C can be a curved slot that is recessed into the elongated structure 330C. Channel 336C can be continuous with a set of holes 334CL and 334CR. The width of the channel 336C can be selected to limit the range of joint movement within the extension structure 330C.

Referring here to both FIGS. 13 and 14, the channel 336C in the articulated compartment 40M is recessed into the elongated structure at an angle of 345 (FIG. 14). The angle 345 may be, for example, an acute angle (eg, 30-60 ° or 45 °) with respect to the surface of the elongated structure 330C in which the channel 336C is located. The channel 336C can be cut into the extension structure 330C using a serrated angle cutter. Alternatively, the elongated structure 330C may be a single molded part. The angle 345 may be selected to increase or decrease the range of motion of the articulated compartment 40M.

Here, with reference to FIG. 15, a drive component 34 and a manipulator 36 with an operably coupled operated component 38 are shown. The drive component 34 can be separated or isolated from the manipulator 36 by the barrier 24. A portion of the barrier 24 can be retained between the drive component 34 and the manipulator 36. The drive component 34 can include several drive elements 60 that can be arranged to act on the driven element 62. The driving element 60 can be driven by at least one force or motion generating element 64. Each driven element 62 can trigger the actuation of an actuator (eg, see 54A in FIG. 4B) within the driven component 38. Alternatively, the driven element 62 may act as an actuator (eg, see 54A in FIG. 4B) to directly actuate the operated component 38. The driven element 60 and the driven element 62 may each be a single element or a grouped set of elements. For example, each drive element 60 may include several individually operable components. Each of these individually operable components may act on an individual or a plurality of contingent components of the individual driven element 62. As a result, each drive element 60 may be controllable via the driven element 62 to trigger the operation of one or more independently operable features of the operated component 38. The number of individually operable elements within each driven element 60 and driven element 62 may be determined, at least in part, based on the number of independently operable features within the operated component 38. good.

Continuing with reference to FIG. 15, the force or motion generating element 64 may be, for example, one or a combination of motors, hydraulic actuation systems, or any other arrangement. In the exemplary configuration, the force or motion generating element 64 is shown as part of the driving component 34. In other configurations, such as those in which hydraulic systems are used, the force or motion generating element 64 may not be completely housed in the drive component 34. For example, the hydraulic master cylinder may be located in the base 30 (FIG. 3) or at another location remote from the drive component 34. The hydraulic wire may then extend from the master cylinder to the drive component 34 so as to act on the drive element 60. It may be desirable to use a fluid-based system for the force or motion generating element 64 to assist in thermal management. In addition, since the master cylinder can be located externally from the robot 16 (FIG. 3), fluid-based systems may allow the drive component 34 to be made with smaller Scherrer.

Continuing with reference to FIG. 15, the driving element 60 can transfer the force to the driven element 62 on the opposite side of the barrier 24. The force may be transmitted from the first barrier side surface 24A to the second barrier side surface 24B (and vice versa) in any of a variety of ways. In some configurations, the force is transmitted by translational displacement of at least a portion of the driving element 60. This displacement can, in turn, cause a displacement of the driven element 62. In other configurations, the force is transmitted by the rotational displacement of at least a portion of the drive element 60. Torque may then be transmitted across the barrier 24 to drive the driven element 62. Still in other configurations, both translation and rotational displacement may be transmitted. The driven element 62 may be driven by both the rotational and translational displacements of the drive element 60. In addition, some driving elements 60 may be controlled by different types of forces or motion generating elements 64. For example, some can be motor driven, while others are controlled by hydraulic systems. In some configurations, the barrier 24 may be substantially or completely stationary when a force is transmitted from the first barrier side surface 24A to the second barrier side surface 24B and vice versa. That is, the barrier 24 may be slightly displaced, but the displacement of the barrier 24 is not necessary and is not the primary means by which force is transmitted. In other configurations, the barrier 24 or part of the barrier 24 is centered around one or more degrees of freedom when the force is transferred, for example, from the first barrier side 24A to the second barrier side 24B. It may be displaced. In some configurations, the degree of freedom in which the barrier 24 is displaced about it may be the same as that of the driving element 60 and / or the driven element 62. In other configurations, the driving element 60 and / or the driven element 62 may be displaced about one or more first degrees of freedom, while the barrier 24 has one or more first degrees of freedom. Displace around the 2 degrees of freedom. For a specific embodiment, the drive element 60 and the accompanying driven element 62 may be displaced about a roll axis, while the barrier 24 is a chapter about an axis (eg, vertical) that traverses the roll axis. You may move it.

Continuing with reference to FIG. 15, in a configuration where torque is transferred from the drive element 60 to the second barrier side surface 24B, the torque does not rotate the barrier 24 material or require a rotation seal within the barrier 24. , Can be substantially or completely relocated. That is, the rotation of the barrier 24 may occur to a small extent, but it is not necessary and thereby torque is not the primary means of transmission to, for example, the second barrier side surface 24B. Various configurations of transmitting such forces across the barrier 24 without rotating the barrier 24 or a portion of the barrier 24 will be described elsewhere herein.

Referring now to FIG. 16, the system 1000 can include a drive component 34 and a manipulator 36 that can be engaged with each other through the barrier 24. The drive component 34 may include a drive element 60. The driving element 60, the driven element 62, and the barrier 24 can be displaced with the same degree of freedom as motion is transmitted across the barrier 24. The drive element 60 can be driven by, for example, but not limited to, a motion generating element such as a motor assembly 70. The motor assembly 70 may include a portion of the drive element 60, eg, a motor 70A for the drive screw 74, a gearhead 70B, and a bearing 70C. The motor 70A may be any suitable various motors such as, but not limited to, brushless DC motors. The gear head 70B may be, but is not limited to, a planetary gear head. The gear ratio of the gearhead 70B may be selected to suit the needs of a given application as will be understood by those of skill in the art. In some configurations, the gear ratio may be 1: 1. The bearing 70C may be, for example, a spindle bearing. The drive element 60 can include, but is not limited to, the drive screw 74 and the nut 76. The drive screw 74 may be, for example, a lead screw or a ball screw, but is not limited to the drive screw 74. When the motor 70A rectifies, the drive screw 74 can rotate. As a result, the nut 76 can move along the length of the drive screw 74. In this configuration, various encoders and sensors measure the movement of the nut 76 along the drive screw 74 and the amount of force transmitted at one or more points in the load path. May be included. To prevent the nut 76 from being displaced with undesired degrees of freedom, the nut 76 may also be mounted along a bearing, such as a linear bearing, which may extend parallel to the drive screw 74. The motor assembly 70 and the drive screw 74 may be replaced by hydraulic cylinders and pistons, respectively, if a hydraulic configuration is desired.

With reference to FIG. 16, the system 1000 can further include, but is not limited to, a nut 76, which may include a protrusion 92 that can extend outward from the drive component housing 72. .. In system 1000, the protrusion 92 can be a blade-shaped ridge. A portion of the nut 76 (ie, protrusion 92) on the outside of the drive component housing 72 may be covered by the barrier 24. In some configurations, the barrier 24 may include preformed or internally glued pockets or sleeves that are continuous with the rest of the barrier 24. These preformed or internally glued pockets may fit around the blade or protrusion 92. Various configurations of the barrier 24 are further described elsewhere herein. The protrusion 92 may project into the manipulator housing 78 and engage the driven element 62. In such a configuration, the driven element 62 may be a block with a slot capable of receiving a blade or protrusion 92. In other configurations, the nut 76 and / or the driving element 60 may be magnetically coupled to the driven element 62 through the barrier 24. As the nut 76 advances along the length of the drive screw 74, the driven element 62 can be displaced. The driven element 62 may be mounted along one or more bearings in the manipulator 36 to constrain the driven element 62 from moving with undesired degrees of freedom.

Still further, with reference primarily to FIG. 16, the driven element 62 may be attached to one or more actuators 54A capable of activating the features of the operated component 38 or the surgical tool 52. good. The actuator 54A can be fixed and moored to the driven element 62 at the mooring point 80. When the driven element 62 is displaced, the actuator 54A may advance in or out of the cutout 266 of the driven component. Since the operated component 38 can be fixedly attached to the manipulator 36, the displacement of the actuator 54A exerts an operating force on or there on the actuated feature of the operated component 38 or the surgical tool 52. Can be done. As will be appreciated by those skilled in the art, any number of driven elements 62 may be included in the manipulator 36 and may be driven by any suitable number of drive elements 60 within the drive component 34. May be good.

Still referring to FIG. 16, each motor assembly 70 can also be associated with one or more position sensors 90 that can be used to provide feedback regarding the position of the components of the drive element 60. The position sensor 90 can be a motor encoder capable of sensing rotation as the motor 70A rectifies. Feedback from the position sensor 90 may be communicated to a remote location from the drive component 34, for example, via a suitable cable or wiring 19 (FIG. 3) in the arm 32, or through wireless communication. Any suitable variety of position sensors 90 may be used. For example, if the position sensor 90 is a motor encoder, any suitable variety of encoders such as optical, magnetic, or capacitive types may be used. In other configurations, the drive element 60 may be associated, for example, with a potentiometer, in addition or as an alternative. Still in other configurations, the nut 76 may include a magnet whose progress is monitored by a position sensor 90, including one or more magnetic sensors such as Hall effect sensors, Hall effect sensor arrays and the like.

With reference to FIG. 17A here, the system 1100 can include a drive component 34 and a manipulator 36 that can be engaged with each other through the barrier 24. The system 1100 can further include a utility component 54 that can enter the operated component 38 through the manipulator housing 78. The utility component 54 may be, for example, mechanical control, light transmission, information transmission, fluid transmission, and / or power or data transmission component. As shown, the utility component 54 does not pass through the barrier 24 and is depicted entirely on one side of the barrier 24. In a configuration in which the barrier 24 acts as a sterile barrier, the utility component 54 may be pre-packaged in a sterile environment. For example, the utility component 54 may be included as part of an assembly, which may include a manipulator 36, which allows the assembly to be packaged in a sterile package, and a component 38 to be operated. Alternatively, the utility component 54 may be individually packaged in its own sterile package. The utility component 54 can be connected to a source 55, which may vary depending on the type of utility component 54. In configurations where the utility component 54 is a mechanical control component, the source 55 may be a motion generating element. In configurations where the utility component 54 can be a fluid transmission component, the source 55 may be an irrigation pump or a blown gas source / reservoir. In a configuration in which the utility component 54 is a light transmissive component, the source 55 may be, for example, a light source for an optical fiber line. In configurations where the utility component 54 is a power transfer component, the source 55 may be a power output, a battery or battery bank, or another power source. In configurations where the utility component 54 is a data transmission component, the source 55 is, for example, a surgical tool 52, eg, a processor capable of transmitting data to and receiving data from, but not limited to, an imaging device. You may.

Here, primarily with reference to FIG. 17B, the system 1200 can include a drive component 34 and a manipulator 36 that can be engaged with each other through the barrier 24. In some configurations, the drive element 60 is hydraulically driven. The system 1200 can include, but is not limited to, a motor assembly 70 that can be attached to the master cylinder 70D. The master cylinder 70D can communicate with the hydraulic line 70E. The hydraulic line 70E can extend from the master cylinder 70D to the slave cylinder 70F. When the motor assembly 70 displaces the piston 70G, the piston 70G may displace the fluid in the hydraulic line 70E. This in turn can cause displacement of the slave piston 70H. In the system 1200, the slave piston 70H can include a protrusion 92 that extends into the manipulator housing 78 and can cause displacement of the driven element 62. The motor assembly 70 and the master cylinder 70D can be located remote from the driven component 34, for example, to reduce the size of the driven component 34 and to simplify thermal management. The motor assembly 70 and the master cylinder 70D may be placed in any suitable location. In some configurations, any motor assembly 70 and master cylinder 70D may be placed within the base 30 (FIG. 3). One or more hydraulic lines 70E from the master cylinder 70D may extend, for example, along the arm 32 (FIG. 3) to one or more slave cylinders 70H.

Here, primarily with reference to FIG. 18, the drive component 34 may include a motor assembly 70. The motor assembly 70 may be powered and commanded from a remote location on the drive component 34. For example, power and commands from the base 30 (FIG. 3) of the controller 15 (FIG. 3) are communicated to the drive component 34 via various cables or wires 19 (FIG. 3) in the arm 32 (FIG. 3). You may. Each motor assembly 70 can also be associated with a motor encoder 90A that senses rotation as the motor of the motor assembly 70 rectifies. Feedback from the motor encoder 90A may be communicated to a remote location from the drive component 34, for example, via a suitable cable or wiring 19 (FIG. 3) in the arm 32 (FIG. 3). The motor assembly 70 can be arranged into the first deck 71A and the second deck 71B, which may be positioned above the first deck 71A so as to minimize the size of the drive component 34. .. The drive component 34 may include, for example, but is not limited to, some first protrusions 92A and some second protrusions 92B. When the motor assembly 70 is fed, the first protrusion 92A and the second protrusion 92B controlled by each motor assembly 70 may be displaced. In some configurations, each first protrusion 92A and each second protrusion 92B can be driven by individual motor assemblies 70. In other configurations, one motor assembly 70 may drive a plurality of first protrusions 92A and a plurality of second protrusions 92B (eg, using a suitable gearing arrangement). For example, in some configurations, one motor assembly 70 may be used to drive the two protrusions 92A, 92B so that they are displaced equally in the same or opposite directions. This allows one actuator (eg, see 54A in FIG. 4B) to be pulled or wound at the same speed as another actuator (eg, see 54A in FIG. 4B) being wound in and out. It may be desirable in the configuration in which the actuator 54A (FIG. 4B), such as a pull wire, is used to actuate the operated component 38 (FIG. 16), as it will help ensure that.

Here, primarily with reference to FIG. 19, the motor assembly 70 and the drive element 60 are shown. The drive element 60 may include a drive screw 74 and a nut 76 that may interface with the drive screw 74. The drive screw 74 may be generally coaxial with the motor assembly 70. The motor assembly 70 can drive the screw 74, and the rotation of the drive screw 74 can cause the nut 76 to travel along the drive screw 74. The protrusion 92 can be shaped such that the force generated in the drive element 60 can be transmitted off-axis to the drive screw 74 and the motor assembly 70. In the specific configuration shown, the protrusion 92 can exert a force along an axis that is substantially parallel to the axis of the motor assembly 70 and the drive screw 74. The protrusion 92 can be an integral part of each nut 76, or the protrusion 92 can be a separate component coupled onto each of the nuts 76. The protrusions 92 may also be attached to each nut 76 in a modular fashion. For example, if the nut 76 drives two driven elements 62, the additional protrusion 92 may be coupled to the nut 76 (or to a protrusion 92 already attached to the nut 76). The nut 76 may be mounted along the bearing. In the exemplary configuration, each nut 76 can have at least one bearing saddle 96, either attached to the nut 76 or, for example, as an integral part thereof. The nut 76 can have, for example, two saddles 96 coupled to the nut 76, but not limited to. The load sensor 98 may be placed in the load path associated with each motor assembly 70. The load sensor 98 may be, for example, but not limited to, a load cell, a strain gauge, or any of the load sensor 98 configurations described herein. The load sensor 98 can provide information about the amount of force transmitted to the operated component 38 (FIG. 16). The load sensor 98 is further described elsewhere herein.

Here, mainly referring to FIG. 20, the drive component 34 is depicted in a state where a part of the drive component housing 72 is removed. Each of the bearing saddles 96 of the nut 76 can travel along the linear motion bearing 94. The linear motion bearing 94 can be, but is not limited to, a dovetail slide bearing. The nuts 76 can be separated on the linear motion bearing 94 so that they do not touch and / or interfere with each other during the operation of the drive component 34. The linear motion bearing 94 for the drive component 34 may include an inner linear motion bearing and an outer linear motion bearing to reduce the vertical dimension of the drive component 34. In some configurations, the linear motion bearing 94 may include two pairs of outer and inner bearings. The outer and inner bearings can be parallel to each other. Each bearing can be shared by two nuts 76. Thus, the configuration adapts to the eight nuts 76, but the longitudinal dimensions of the linear motion bearing 94 need to be larger than necessary to adapt to the two nuts 76 with sufficient spacing between them. There is no. The inner distance 93 between the protrusions 92A, 92B can be minimized to reduce the occupied area of the manipulator 36 (FIG. 16). The first protrusion 92A and the second protrusion 92B can each be "L" shaped. The "L" shaped leg 99 can be sized so that the vertical span 101 can be aligned in the desired plane. The morphology of the protrusions 92A, 92B may vary depending on the configuration. For example, instead of including the bend or forming an "L", the protrusions 92A, 92B may extend at an angle from the body of the nut 76. The angle can allow a linear path from the nut 76 to the axis on which the force can be transmitted. Arc-shaped or "S" -shaped, and other non-linear protrusions 92A, 92B may also be used. In other configurations, for example, where the number of protrusions 92A and 92B on the nut 76 is greater than 1, not all protrusions 92A, 92B need to be aligned on the same plane. Alternatively, protrusions 92A, 92B connected to a single nut 76 may be, for example, on parallel planes.

Here, primarily with reference to FIG. 21, alternative exemplary configurations of motor assembly 70 and drive element 60 are shown. The configuration of the linear motion bearing 94 (FIG. 20) that can guide the advancement of the nut 76 can be a first linear needle bearing assembly 91A and a second linear needle bearing assembly 91B. The linear needle bearing assemblies 91A, 91B may be highly rigid and may be subject to high moment loads which may be present with the nut 76 having a protrusion 92 which transmits force to an off-axis location. The linear needle bearing assemblies 91A, 91B can be, for example, but not limited to, a "V" shape, respectively, and can serve as a wiring path for the roller cage 71D (FIG. 23) of the linear needle bearings 91A, 91B. It is possible to have a housing 79 including an inner surface 79A. In other configurations, another component of the linear needle bearing assemblies 91A, 91B may provide a wiring line instead of the housing 79. The outer surface 79B of the housing 79 may be arcuate or rounded to allow the linear needle bearing assemblies 91A, 91B to be compact. The nut 76 can be held in place between the linear needle bearing assemblies 91A, 91B. The gap 79C between the first linear needle bearing assembly 91A and the second linear needle bearing assembly 91B allows the protrusion 92 to extend away from the nut 76 and transfer force to the desired axis. be able to. The desired axis can be an axis along which the driven element 62 (FIG. 16) can be displaced. A traveling limiter 57 (FIG. 23) may be included in the linear needle bearing assemblies 91A, 91B to prevent movement of the nut 76 outside the predetermined range. The advance limiter 57 (FIG. 23) may be a mechanical stop such as a wall that blocks the advance of the nut 76 in various configurations.

Here, mainly referring to FIG. 22, the inner cross section obtained in I (FIG. 21) is shown. Includes a nut 76, which can be constructed to be used with any of a variety of different protrusions 92. Specifically, the nut 76 can include a receptive feature 75 into which the protrusion 92 can be attached. Each of the various different protrusions 92 may include a portion that may fit within the receiving feature 75. The desired protrusion 92 can be removably coupled to the nut 76 via fasteners 77, for example, but not limited to. Any suitable fastener 77 may be used. In the alternative configuration, the protrusions 92 do not need to be removably coupled and may be ultrasonically welded, solvent bonded, glued, or otherwise permanently attached to the nut 76. A load sensor 98 capable of measuring the load in the load path of the drive element 60 is also included in FIG.

Here, with reference primarily to FIG. 23, some exploded views of the linear needle bearing assemblies 91A, 91B are shown. The linear needle bearing assemblies 91A, 91B may include a housing 79. The outer surface 79B of the housing 79 can be arcuate or rounded. The first recess 79D and the second recess 79E can be included in the outer surface 79B and can hold the two housings 79 when the linear needle bearing assemblies 91A, 91B are fully assembled. It can be sized to work with the 79F. In an exemplary configuration, the retention device 79F can be a retention ring or any other suitable retention device 79F, such as, but not limited to, a C-clip, pin, and / or threaded fastener. It is not limited to. The inner surface 79A can, but is not limited to, be substantially "C" shaped and can serve as a wiring path for the needle bearings 71C of the linear needle bearing assemblies 91A, 91B. The linear needle bearing assemblies 91A and 91B can each include, for example, 12 needle bearings 71C. The number of linear needle bearings 71C in the linear needle bearing assemblies 91A, 91B may vary depending on the size of the needle bearing 71C and the force expected to be present on the needle bearing 71C. In some configurations, the needle bearing 71C may be 1 to 2 mm in diameter and 12 needle bearings 71C may be included in one linear needle bearing assembly 91A, 91B. The needle bearings 71C may be received in the needle bearing cage 71D, respectively, when the linear needle bearing assemblies 91A, 91B are fully assembled. The needle bearing cage 71D can be molded so as to fit into the inner surface 79A of the housing 79 and allow the needle bearing 71C to utilize the inner surface 79A as a wiring path.

Continuing with reference to FIG. 23, the nut 76 can include a first portion 76A and a second portion 76B. The first portion 76A and the second portion 76B may be coupled together when assembled. In the alternative configuration, the nut 76 may be a single monolithic component. The nut 76 may be shaped to allow the needle bearing cage 71D to fit around the nut 76 when the linear needle bearings 91A, 91B are fully assembled. In an exemplary configuration, the first portion 76A of the nut 76 adapts to the "C" -like shape of the needle bearing cage 71D, and the needle bearing 71C serves as a guide groove outside the first portion 76A of the nut 76. It can be molded to allow it to be used. The first portion 76A can, but is not limited to, an octagonal cross section. The nut 76 may be adapted to translate and displace in response to the rotational displacement of the drive screw 74. In an exemplary configuration, the second portion 76B may be engaged with the drive screw 74 and the second portion 76B may be translated and displaced. The nut 76 may be displaced when the second portion 76B is attached to the first portion 76A. The second portion 76B may vary depending on the type of drive screw 74 used. For example, the second portion 76B may be a ball nut if a ball screw is used. If a lead screw is used, the second portion 76B may be a split nut, half nut, or other suitable type of nut. Alternatively, the second portion 76B may include a threaded receptive feature that can be screwed onto the drive screw 74.

Still further, with reference primarily to FIG. 23, each needle bearing cage 71D can include slot 71E (only slot 71E of linear needle bearing assembly 91A is visible in FIG. 23). Slot 71E can cooperate with the progress limiter 57 extending from the first portion 76A. The advancing limiter 57 can be, for example, a protrusion or ridge that can extend outward from the first portion 76A, without limitation. When fully assembled, the progress limiter 57 extends into slot 71E. When the nut 76 advances within the linear needle bearing assemblies 91A, 91B, the advance limiter 57 can prevent the needle bearing cage 71D and the needle bearing 71C seated therein from moving beyond a predetermined range. For example, the advance limiter 57 may be adopted to prevent the needle bearing cage 71D and the needle bearing 71C from advancing out of the housing 79. At the end of the displacement range enabled by the advancing limiter 57, the advancing limiter 57 may abut against the edge of slot 71E. At this point, the needle bearing cage 71D and needle bearing 71C may not be able to be further displaced in that direction and progress will be effectively limited using mechanical stops. The lengths of slots 71E can be, but are not limited to, substantially equal. In the alternative configuration, the progress limiter 57 may not be included on the nut 76, but may be included on the housing 79. For example, in some configurations, a ridge that can serve as a progress limiter 57 may extend from the inner surface 79A into the slot 71E. In other configurations, the inner surface 79A may include one or several raised features that can limit the displacement range of the needle bearing 71C and the needle bearing cage 71D. At least one key feature is included on one or both of the linear needle bearing assemblies 91A, 91B to prevent the linear needle bearing assemblies 91A, 91B from rotating about the axis of the drive screw 74. May be good. The key feature may be, for example, a protrusion extending from the housing 79 that would encounter a stationary element acting as mechanical interference. Alternatively, protrusions from the stationary element may extend into the receiving structure within the linear needle bearing assemblies 91A, 91B. In some configurations, rotation may be blocked by fitting the protrusion 92 into the notch 75B in the receiving structure 75 of the nut 76.

Still referring to FIG. 23, the nut 76 can be constructed to be used with any of a variety of different protrusions 92. Specifically, the nut 76 can include a receptive feature 75 into which the protrusion 92 can be attached. The receiving feature 75 can be a recess into the nut end 75A. The receptive feature 75 may also include a notch 75B to accommodate a portion of the receptive feature 92 as it is bound into the receptive feature 75. Any suitable method for binding the protrusion 92 into the receiving feature 75 may be used. Fastener 77 (FIG. 22) may be used in several configurations. Alternatively, the protrusion 92 may be permanently bound into the receptive feature 75.

Here, mainly referring to FIG. 24, the drive element 60 can be operated electro-hydraulic. The drive element 60 may include, for example, but is not limited to, a hydraulic slave cylinder 70F. The slave cylinder 70F can include a piston 70H (see FIG. 17B) that can be displaced to cause displacement of the protrusion 92. The protrusion 92 may act on the driven element 62 (FIG. 17B) to activate the features of the operated component 38 (FIG. 17B). The slave piston 70H may be guided by at least one linear motion bearing 94. Any suitable linear motion bearing 94, such as, but not limited to, those described in FIG. 23 and elsewhere herein may be used. The protrusion 92 may be an integral part of the slave piston 70H (FIG. 17B) in some configurations. In an alternative configuration, the slave piston 70H (FIG. 17B) may be constructed to be used with any of a variety of different projections 92. Specifically, the slave piston 70H (FIG. 17B) can include a receptive feature (similar to the receptive feature 75 of FIG. 23) into which the protrusion 92 can be attached. In some configurations, the intervention body (not shown) may be included between the slave piston 70H (FIG. 17B) and the protrusion 92. In such a configuration, the displacement may be transmitted to the protrusion 92 through the intervention body. A hydraulic master cylinder 70D can be included to drive the slave cylinder 70F through the hydraulic line 70E. The hydraulic master cylinder 70D can be driven by the motor assembly 70. The motor assembly 70 may cause displacement of the piston 70G (see FIG. 17B) within the master cylinder 70D. When the piston 70G (FIG. 17B) is displaced, the master cylinder 70D and the slave cylinder 70F are connected via the hydraulic line 70E, so that the slave piston 70H (FIG. 17B) in the hydraulic slave cylinder 70F is the result. May be displaced. To monitor the displacement, the position sensor 90 may be associated with another component, such as a part of the motor assembly 70 or the drive element 60. At least one pressure sensor 70I may also be included to monitor the pressure in the hydraulic line 70E.

Referring here to FIG. 25, the motor assembly 70 may include a motor 70A for the drive screw 74A, a gearhead 70B, and a bearing 70C. The rotation of the drive screw 74A may in turn cause a translational displacement of the nut 76A. The nut 76A may move in cooperation with the master cylinder piston 70G. In some configurations, the master cylinder piston 70G and nut 76A may be coupled to each other. When the master cylinder piston 70G is displaced, the fluid in the attached hydraulic line 70E may also be displaced. The head 70J of the master cylinder piston 70G can include some sealing member 70K, eg, an O-ring or similar gasket member that can ensure that fluid does not escape from the hydraulic line 70E, without limitation. The pressure tap 70L can be attached to the wiring 70M leading to at least one pressure sensor 70I. The pressure sensor 70I may collect data related to the pressure in the hydraulic line 70E via the pressure tap 70L and the wiring 70M. Data from at least one pressure sensor 70I may be provided to the controller as feedback.

Primarily with reference to FIG. 26, the load sensor 98 (FIG. 20) may be associated with each motor 70 (FIG. 20) in the drive component 34 (FIG. 20). The load sensor 98 (FIG. 20) may be any of a variety of conventional load sensor types. Alternatively, the load sensor 98 (FIG. 20) may have electrical components that are remote from the load path and can be physically isolated, for example. The load sensor 98 (FIG. 20) may include, for example, a mechanical component 150 placed in a load path that can be deformed or displaced in proportion to the load. This deformation may in turn be sensed or monitored by the electrical components of the load sensor 98 (FIG. 20) located remote from the load path. The mechanical component 150 may include, but is not limited to, a flexible member which may be the deformable body 152A. The deformable main body 152A may have a first end portion 151A and a second end portion 151B. The exemplary deformable body 152A shown in FIG. 26 is unloaded. The deformable body 152A can be molded, for example, as an "S" beam. In other configurations, the shape of the deformable body 152A may be any shape or configuration. The mechanical component 150 may optionally include a protrusion or flag 154 capable of amplifying any deformation of the deformable body 152A. The protrusion 154 may be coupled onto the deformable body 152A or may be an integral part of the deformable body 152A.

Primarily with reference to FIG. 27, when a load 156 is applied to at least one of the first end 151A and the second end 151B, at least a portion of the deformable body 152A has its unloaded shape. It can be distorted from (see, for example, FIG. 26). The shape of the deformable body 152A may be selected based on where distortion is desired to occur or how it is desired that the deformable body 152A will be distorted. The transverse component 153A can be distorted by receiving a load 156. More specifically, the angle 153B of the transverse component 153A with respect to the first end 151A and the second end 151B can be changed. The amount of distortion may be sensed or monitored to determine the load 156 applied to the mechanical component 150.

Still referring to FIG. 27, the amount of distortion that can occur for different ranges of load 156 on the deformable body 152A may be controlled by modifying the shape and / or structure of the deformable body 152A. In some configurations, it is desirable that the deformable body 152A be deformed by a larger amount or at a larger rate under the first range of loads, as opposed to the second range of load conditions. obtain. For example, it may be desired that the deformable body 152A be distorted by a larger amount or at a greater rate under low load conditions than under high load conditions. This may allow the deformable body 152B to be displaced by a greater amount under the load conditions expected in a given device. In a specific configuration, the deformable body 152A can be constructed such that the first range of loads 156 can include loads of 0 to 50 pounds. A second range of loads 156 can include, for example, any load 156 above 50 pounds. In the first range of the load 156, the deformable body 152A may be freely distorted in proportion to the load 156. In the second range of the load 156, the deformable body 152A may be more elastic to distortion or may not be substantially distorted.

Referring here to FIG. 28A, the mechanical component 150B may include a deformable body 152C that may include a stop projection 153 that may extend towards the transverse component 153A. As the load 156 increases on the deformable body 152C, the gap 153D between the stop projection 153 and the transverse component 153A can be reduced. Eventually, the transverse component 153A will contact the stop projection 153 and prevent continuous displacement as the load 156 increases. The amount of load 156 in which this contact can occur may be the upper limit of the first load range. In some specific configurations, the amount of load 156 at which contact occurs can be, for example, 50 pounds, but not limited. The amount of load at which contact occurs can be controlled based on the structure, material, and geometry of the deformable body 152C. The deformable body 152C is therefore constructed so that the distortion of the deformable body 152C can provide higher resolution of the load 156 under low load conditions or within the first range of the load. good. Target resolution can be, for example, but not limited to, less than 0.1 pound. In some configurations, the target resolution within the first range of load conditions may be less than 0.1 pound, while the mechanical component 150B is more binary within the second range of load conditions. A type indication may be provided. For example, within a second range of load conditions, the mechanical component 150B serves to provide a "yes" or "no" indication of whether the amount of load 156 applied is within the second range. May be fulfilled.

Primarily with reference to FIG. 28B, the mechanical component 150C may include a threaded insert 166A instead of the stop projection 153 (FIG. 28A). The threaded insert 166A may be advanced or retracted out of the deformable body 152D by a desired amount so as to modify the size of the gap 153D. The movement of the threaded insert 166A may change the point at which the stop 166E can be encountered, or may modify the force required before the stop 166E is encountered. Therefore, the load range is flexible and may be user-defined, for example. The threaded insert 166A and / or the deformable body 152D can indicate the amount of load 156 to which the stop 166E will be contacted to facilitate demarcation of the desired range, marking 166G. May include. In an exemplary configuration, the threaded insert 166A shown provides a compression stop.

Referring here to FIG. 28C, the mechanical component 150D may include a threaded insert 166A to provide a tension stop. The threaded insert 166A may be inserted through the deformable body 152E and moored into the stationary element 166H. This may be achieved using screw engagement. The threaded insert 166A may also be partially or completely screwed, or not screwed at all, but instead may be glued / welded to the stationary element 166H, or fixed, It may be attached to the rest element 166H using a tight fit or any other arrangement. The threaded insert 166A does not affect the distortion of the deformable body 152E until the gap 153E is reduced to zero and the deformable body 152E encounters the head or stop 166E of the threaded insert 166A. May be good.

Referring here to FIG. 28D, the deformable body 152E may be distorted when tension 156 is applied into the mechanical component 150E. The angle 153B (FIG. 27) of the transverse component 153A with respect to the first end 151A and the second end 151B of the deformable body 152E may be changed. Applying tension can stretch and stretch the deformable body 152E. Since the threaded insert 166A can be fixed and coupled to the stationary element 166H, the deformable body 152F has a first end 151A of the deformable body 152E attached to the head 166E of the threaded insert 166A. It may only be stretched by tension until it abuts.

Referring here to FIG. 28E, the manner in which the deformable body 152G can be distorted can also be influenced by the shape of the deformable body 152G. In some configurations, the deformable body 152G may be coupled or mounted on a component of the drive system that may be displaced due to the runout of a portion of the drive system. To mitigate any effects of runout, or to allow for more generous runout tolerances, the mechanical component 150F is due to any rotation around the secondary axis, or any drive shaft. It may be constructed to have a low tendency to displace as a result of other rotational eccentricities. The deformable body 152G can include several thinned spans 162 that can be defined by channels 164 that are recessed or cut out through the deformable body 152G. The outer portion 163 of the deformable body 152G is relatively thick and can serve as a buttress against distortion due to runout. The outer portion 163 of the deformable body 152G may also serve to accommodate the threaded insert 166A (FIG. 28D). At least one side surface of the deformable body 152G can include a gap 168. The form and arrangement of the deformable body 152G and the channels 164 and the thinned span 162 may be selected to make the deformable body 152G elastic against undesired distortions. In some configurations, the morphology of the deformable body 152G and the arrangement of the channels 164 and the thinned span 162 can make the deformable body 152G generally behave as some four-bar connection. Such a parallelogram frame configuration may reinforce the deformable body 152G against undesired deformation. Additional channels 164 and thinned compartments 162 may be added to increase the amount of distortion caused by a given load. The mechanical component 150F can also include a stop surface 166. When the deformable body 152G is pressured and distorted, the gap 168 between the stop surface 166 and the rest of the deformable body 152G can be reduced until contact is made with the stop surface 166. The stop surface 166 can limit or prevent distortion of the deformable body 152G when the load on the deformable body 152G reaches a desired amount. The mechanical component 152G can, for example, respond to a first range of loads rather than a second range of loads, without limitation. The stop surface 166 may be replaced or replenished with the threaded insert 166A (FIG. 28D). In configurations that include a flag or protrusion 154, the protrusion 154 may be sized to produce the desired amount of amplification of the distortion of the deformable body 152G. When a load 156 (FIG. 28D) is present, the displacement of a point above a portion of the most distal projection 154 of the deformable body 152G is the length of the projected multiplied radian angle of the projection 154 with respect to its unloaded position. Will be about equal. The longer protrusion 154 may be used to generate further amplification.

Referring here to FIG. 29, the load sensor 98A may include an electrical component 160A, eg, but not limited to, a potentiometer. When the electrical component 160A is a potentiometer, the wiper can change the resistance and move across the resistance element of the potentiometer when the projection 154 is displaced. By measuring the resistance, it is possible to determine the amount of displacement of the protrusion 154. Since the amount of displacement is proportional to the load 156, the load sensor 98A may use the measured resistance value to determine the load 156.

Referring here to FIG. 30A, the load sensor 98B may include an electrical component 160B, such as, but not limited to, an optical sensor. Any variety of optical sensors, such as, but not limited to, laser displacement sensors may be used. Alternatively, a camera may be used to monitor and track the location of the protrusion 154 over time. In some configurations, the protrusion 154 comprises a grid or pattern, color marking, or equivalent that can aid in tracking the displacement of the reference reference 157, eg, but not limited to, the protrusion 154, and thus determining the load 156. But it may be.

Referring here to FIG. 30B, the load sensor 98D may include an electrical component 160E. The electrical component 160E may include a light emitter 160F and a receiver 160G. The light emitter 160F may illuminate light on the reflective projection 154A on the mechanical component 150. The reflecting projection 154A may reflect light from the light emitter 160F to the light receiver 160G. As the load 156 on the mechanical component 150 changes, the orientation of the reflective projections 154A may also change. As a result, the light reflected from the reflector 154A may be reflected to different parts of the receiver 160G. The illuminant 160F may include, for example, one or more lasers or concentrated light beam emitters. The reflective projection 154A may include a brightly colored surface or mirror surface on which light from the light emitter 160F can be projected. The receiver 160G may include an array of one receiver 160G or receiver 160G, which can be a reflective receiver such as an optical sensor. If the mechanical component 150 is distorted in proportion to the load 156, the location and / or intensity of the reflected light may be tracked and therefore the determination of the load 156 may be made.

Referring here to FIG. 30C, the load sensor 98E can include an electrical component 160H. The electrical component 160H may include a light source 160I and an optical sensor 160J. The optical sensor 160J may include, for example, a camera having a CCD or CMOS chip. The light source 160I may generate light capable of illuminating a portion of the protrusion 154. The optical sensor 160J may be placed so that the shadow of the protrusion 154 is within the field of view of the optical sensor 160J. The position of the shadow may be tracked by the optical sensor 160J, and therefore the load 156 may be determined. In some configurations, the light source 160I may be placed on one side surface of the protrusion 154, while the optical sensor 160J may be placed on the opposite side of the protrusion 154. Alternatively, or in addition, the protrusion 154 may include one or more slits, slots, voids, openings, or equivalents 154B through which light from the light source 160I can pass. The slit 154B may change location as the protrusion 154 displaces in proportion to the load 156 on the mechanical component 150. The optical sensor 160J may monitor the location of the slit 154B instead of or in addition to the location of the shadow of the projection 154 so as to determine the amount of distortion of the mechanical component 150. The distortion may be analyzed to determine the load 156 on the mechanical component 150.

Referring here to FIG. 31A, the load sensor 98C may include an electrical component 160C, eg, a magnetic sensor such as, but not limited to, a Hall effect sensor or a Hall effect sensor array. In such a configuration, at least one magnet 158, such as, but not limited to, a neodymium rare earth magnet may be attached to or embedded in the protrusion 154. In a configuration in which the electrical component 160C includes a Hall effect sensor, the Hall effect sensor determines the position of the protrusion 154 based on the Hall voltage generated by the magnetic field of at least one magnet 158 when the protrusion 154 is displaced. May be used for. Any number of other sensing sequences, such as, but not limited to, volumetric, ultrasound, and guided sensing may be used.

Referring here to FIG. 31B, the load sensor 98F may include an electrical component 160K with a non-contact sensor. The sensor may be, for example, an inductive or capacitive sensor. As the protrusion 154 displaces in proportion to the load 156 on the mechanical component 150, the capacitance and inductance may change as expected based on the location of the protrusion 154. Capacitance and inductance values may be monitored to determine the location of the protrusions 154 and, as a result, the amount of load 156 on the mechanical component 150.

Here, primarily with reference to FIGS. 32 and 33, the mechanical component 150H can include an "S" beam 170. The protrusion 174 can be coupled to the central transverse component 172 of the "S" beam 170. The protrusion 174 may be attached to the central transverse component 172 in any suitable manner, for example, but not limited to, via fasteners. Alternatively, the projection 174 may be integrally formed as part of the "S" beam 170. The ratio of the length of the protrusion 174 to the "S" beam 170 can be, but is not limited to, about 3: 1. The void 176 can extend through the "S" beam 170 in a direction substantially parallel to the projection 174 when the projection 174 is in the no-load position. The void 176 can be sized to accommodate the drive screw 74 (FIG. 16) or other portion of the drive element 60 (FIG. 16). In some configurations, the void 176 may be sized so that at least a portion of the motor assembly 70 (FIG. 16) can be placed inside the void 176. The "S" beam 170 can also include a stop projection 175 (described elsewhere herein). The mechanical component 150H may also include, but is not limited to, a mounting feature 178 with a raised plateau with threaded holes 178A. The "S" beam 170 includes mounting features 178 to help ensure that any displacement of the "S" beam 170 is the result of a load deviation in the load path associated with the "S" beam 170. It can be used and attached to a stationary housing (eg, drive component housing 72 (FIG. 18)). In other configurations, the mounting feature 178 may be a mounting bracket or rail. In other configurations, a plurality of mounting features 178 may be included. For example, the mounting feature 178 may be included on both the first surface 170A (FIG. 32) and the second surface 170B (FIG. 33) of the "S" beam 170. The "S" beam 170 is also a motor assembly 70 (FIG. 16), a bearing (linear needle bearing assembly 91A (FIG. 21) and 91B (FIG. 21), etc.), or a drive element 60 (FIG. 16). ) Can also include some threaded holes 179 that may allow it to be coupled to other parts.

Here, referring to FIG. 34, an enlarged view of the region J in FIG. 33 is drawn. The "S" beam 170 can include a stop projection 153. The gap 153D can exist between the stop projection 153 and the transverse component 172. The transverse component 172 can include a thin or flexible portion 180 that is most proximal to the body of the "S" beam 170. The thin portion 180 may be included in each end of the transverse component 172. The thin portion 180 can act as an elastically deformable compartment. Due to structural strength, the thin portion 180 can have, for example, but not limited to, an arched wall 180A. In other configurations, this does not have to be the case. The location and thickness of the thin portion 180 may be chosen to help the "S" beam 170 have the desired displacement behavior under given load conditions. In addition, the material selected for the "S" beam 170 may be selected for its modulus of elasticity and yield strength, among other properties. Possible materials can include, but are not limited to, any metal, composite material, and other materials such as plastics, magnesium, steel, aluminum, and titanium. Materials such as plastic or magnesium may be used in applications where low load is expected. For high load applications, materials such as steel may be used. In other applications, materials such as aluminum or titanium may be used.

Primarily with reference to FIG. 35A, the mechanical component 150I may include a deformable body 173 that may be designed to mitigate any effect of runout on the deformable body 173 during operation. The deformable body 173 also has a deformable body 173 such as a stationary housing (eg, drive component housing 72 (FIG. 16)), a motor assembly 70 for the associated drive train (see FIG. 35B), and / or bearings. It can also include several mounting points 181 that can be attached to (eg, linear needle bearings 91A and / or 91B (FIG. 21)). The void 176 can be sized so that the motor assembly 70 (FIG. 35B) can be accommodated at least partially within the deformable body 173. In addition, the void 176 is sized to allow the drive screw 74 to extend into the deformable body 173 and engage with the motor assembly 70 (FIG. 35B) housed therein. Can be done.

Still referring to FIG. 35A, the deformable body 173 can include a flag or protrusion 174A that can be coupled to it. The protrusion 174A can be mounted in the shoe 175A. The protrusions 174A and / or shoes 175A may include detents or step features that may help position and / or lock the protrusions 174A in place when the mechanical component 150I is assembled. In an alternative configuration, the shoe 175A can allow the protrusion 174A to slide back and forth along the axis 175C of the protrusion 174A, for example, but not limited to. Therefore, the displacement of the magnet 158 in the projection 174A with respect to a given load can be modified. When the protrusion 174A is slid to a certain position, one or more set screws or equivalents may be used to hold the protrusion 174A in place. The protrusion 174A can also include a cutout 173A that may allow the protrusion 174A to be slightly compressed when inside the shoe 175A. The cutout 173A can allow the compartment of the protrusion 174A received in the shoe 175A to act as a spring, which can exert a force on the wall 175D of the shoe 175A. This force can help retain the protrusion 174A in the shoe 175A. The protrusion 174A can include a bend 175E that may place a magnet 158 behind and / or along the motor assembly 70 (FIG. 5) and possibly save space. The bending portion 175E may divide the protrusion 174A into a bending front portion 174F and a bending rear portion 174G. If desired, a magnetic shielding material such as mumetal may be included to shield a portion of the motor assembly 70 (FIG. 16) and / or the protrusion 174A. The protrusions 174A may differ from the shapes described herein. The shape or morphology of the protrusion 174A can be selected to best fit any spatial constraint that may exist in a variety of applications.

Here, referring to FIG. 35B, the load sensor 98 can include a mechanical component 150J and an electrical component 160. The void 176 in the mechanical component 150J can be sized so that the motor assembly 70 can be housed in the deformable body 173 at least partially. The motor assembly 70 may be attached to the mechanical component 150J via the mounting point 181. In addition, the void 176 can be sized to allow the drive screw 74 to extend into the deformable body 173 and engage with the motor assembly 70. When the flag or protrusion 174B is displaced, the magnet 158 attached to the protrusion 174B is within the range of several Hall effect sensors 160D arranged on the PCB 210 included as part of the electrical component 160 of the load sensor 98. May be swept along the path of. The data provided by the Hall effect sensor 160D may be processed by the controller 15 (FIG. 1) to determine the location of the magnet 158. Positional data can be used to determine the amount of load 156 (FIG. 31) because the location of the magnet 158 depends on the amount of load 156 (FIG. 31) applied to the mechanical component 150J. The electrical component 160 consisting of a Hall effect sensor array was filed on December 21, 2012 in System, et al.
It may be similar to that described in US Patent Publication No. 20130184676, entitled Methods, and Apparatus for Estimating Liquid Delivery.

Referring here to FIG. 35C, the mechanical component 150J can include insert 166A, which can be a threaded insert extending into or through the deformable body 173. The mechanical component 150J can also include an adjustable spacer such as a nut 167 on the threaded insert 166A. The threaded insert 166A and nut 167 can provide a compression and tension stop for the deformation of the deformable body 173. The threaded insert 166A is used to deform the deformable body 173 by a larger amount or at a larger rate under the first range of loads, as opposed to the second range of load conditions. May be used.

Also with reference to FIGS. 35D-35E (enlarged views of regions 35D and 35E, respectively in FIG. 35C), in an exemplary configuration, the threaded insert 166A and nut 167 have a tension stop gap 166B (FIG. 35D). ) And the compression stop gap 166C (FIG. 35E) are arranged so as to be present. The tension stop gap 166B (FIG. 35D) can occupy the space between the first surface 166D (FIG. 35D) of the threaded insert and the first surface 173C (FIG. 35D) of the deformable body. .. The compression stop gap 166C (FIG. 35E) can occupy the space between the nut surface 167A (FIG. 35E) and the second surface 173D (FIG. 35E) of the deformable body 173. The second surface 173D (FIG. 35E) can be on the opposite side of the deformable body 173 from the first surface 173C (FIG. 35D). The size of the tension stop gap 166B (FIG. 35D) may be selected to define a first range of tension loading conditions over which the deformable body 173 can be distorted or deformed substantially freely. Loads within the second tensile load range outside the first tensile load range are deformable because the stop provided by the threaded insert 166A (FIG. 35D) can be encountered and further distortion can be prevented. It can cause little or no distortion of 173. The size of the compression stop gap 166C (FIG. 35E) may be selected to define a first range of compression load conditions over which the deformable body 173 can be distorted or deformed substantially freely. Loads within the second compression load range outside the first compression load range are encountered by stops provided by threaded inserts 166A (FIG. 35D) and nuts 167 (FIG. 35E) to prevent further distortion. As such, it can cause little or no distortion of the deformable body 173. In some configurations, the threaded insert 166A (FIG. 35D) is the desired amount inside or outside the deformable body 173 to alter the size of the gaps 166C (FIG. 35E) and 166B (FIG. 35D). You may move forward or backward with. Forward or backward can, in turn, modify the load encountered by the stop. The range is flexible and may be user-defined, for example. The threaded insert 166A (FIG. 35D) and / or the deformable body 173 applies the amount of load 156 (FIG. 28A) to which the stop will be contacted to facilitate demarcation of the desired range. Marking 166G (FIG. 28B), which can be shown, may be included.

Referring here to FIG. 35D, the tension stop gap 166B can be reduced when tension is applied to the deformable body 173. The mechanical stop can be encountered when the first surface 166D of the head 166E of the threaded insert 166A and the first surface 173C of the deformable body 173 come into contact. The force with which the surfaces 166D, 173C come into contact may be the boundary between the first tensile load range and the second tensile load range. In addition, the head 166E of the threaded insert 166A has a second nut (not shown) capable of engaging a thread (not shown) on the end of the threaded insert 166A. It may be replaced. The second nut can be advanced along the thread to modify the size of the tension stop gap 166B. The second nut may be placed in a suitable position for the desired first tensile load range.

Here, referring to FIG. 35E, the compression stop gap 166C can occupy the space between the first surface 167A of the nut and the second surface 173D of the deformable body. The size of the compression stop gap 166C may be selected to define a first range of compression load conditions over which the deformable body 173 can be substantially freely distorted or deformed. When the compressive force is applied to the deformable body 173, the compression stop gap 166C can be reduced. The mechanical stop can be encountered when the first surface 167A of the nut 167 and the second surface 173D of the deformable body 173 come into contact. The force that these surfaces 167A, 173D come into contact with may be the boundary between the first compression load range and the second compression load range. Nuts 167 of different sizes may be used to modify the size of the compression stop gap 166C. The nut 167 used may be selected to accommodate the desired force value for the first compression load range.

Primarily with reference to FIG. 35F, the threaded insert 166A may extend through the threaded insert receiving hole 173E. In some configurations, less than the entire portion of the threaded insert 166A can be screwed in, and the threaded insert 166A is screwed into engagement with the threaded insert receiving hole 173E. It does not have to be. The configuration in which the less than whole portion of the threaded insert 166A can be screwed can allow the deformable body 173 (FIG. 35C) to freely distort over a desired load range. In some configurations, only a portion of the threaded insert 166A into which the nut 167 is meshed may be screwed. The threaded insert 166A can include a threaded mounting hole 166F. The threaded mounting hole 166F can allow the fastener 169 to be coupled into the threaded insert 166A. Fasteners 169 secure the threaded insert 166A to a stationary element or structure 166H that can ensure that the threaded insert 166A does not displace during the load of the deformable body 173 (FIG. 35C). May be combined. In other configurations, any other suitable method of fixing the position of the threaded insert 166A may be used.

Here, primarily with reference to FIG. 36, the motor assembly 70 can be arranged to apply a force to the drive screw 74. The array including the motor assembly 70 and the drive screw 74 can include the mechanical component 150K. The mechanical component 150K can include an "S" beam 170. The coupling block 203 can be attached to the motor assembly 70 and, in some configurations, can be used to facilitate the coupling of the motor assembly 70 to the "S" beam 170. The coupling block 203 can include, for example, but not limited to, a threaded hole 209 that may allow the fastener (not shown) to couple the "S" beam 170 to the coupling block 203. Any other suitable means of coupling the motor assembly 70 to the "S" beam 170 may be used. The flag or protrusion 174A attached to the "S" beam 170 can extend parallel to the vertical axis 200A of the motor assembly 70 and has a gap 200B (FIG. 37) covering the motor assembly 70. This configuration can reduce the size of the load sensor 98 (FIG. 35B) and the motor assembly 70 pair.

Here, mainly referring to FIG. 37, the drive screw 74 can pass through the void 176 in the "S" beam 170. The mounting feature 178 may be included on the "S" beam 170 and may be used to couple a portion of the "S" beam 170 to a stationary structure or housing 166H. In some configurations, the motor assembly 70 is self-floating and is not fixed and coupled to the stationary housing 166H. The motor assembly 70 and the drive screw 74 may be displaced as the load in the drive path increases. The "S" beam 170 is coupled to the motor assembly 70, but is fixed to the rest housing 166H, so that the "S" beam 170 can be deformed as a result of this displacement. In other configurations, another part of the drivetrain can be floating. For example, the end 202C of the lead screw 74 driven by the motor assembly 70 may be retained in a slip joint (not shown). Alternatively, the motor assembly 70 may include a gearhead 70B (FIG. 36) that is wide enough for the gears to allow some axial displacement between them during operation.

Referring here to FIG. 38, the “S” beam 170 of some load sensors 98 (FIG. 35B) can be included in the drive component 34. In configurations where the motor assembly 70 is free-floating or not fixed and coupled to the drive component 34, the motor assembly 70 is slightly displaced when the load is applied to the motor assembly 70 through the associated drive screw 74 (FIG. 37). It may be displaced. The displacement may distort the "S" beam 170 (FIG. 37). The distortion of the "S" beam can displace the protrusion 174 from an orientation that is substantially parallel to the motor assembly 70. The displacement of the protrusion 174 may be read by a sensor on the electrical component 160 (FIG. 35B) of the load sensor 98 (FIG. 35B). In some configurations, the sensor may be at least one Hall effect sensor 160D capable of tracking the position of the magnet 158 on the protrusion 174. Electrical components 160 (FIG. 35B) such that one or more sensors, such as the Hall effect sensor 160D, allow mutual comparison between the Hall effect sensor 160D when any one of the projections 174 moves. ) Can be included on the PCB 210. Such reciprocal comparisons may help detect displacements of protrusions 174 with a greater degree of certainty, provide redundancy in the system, and be useful in failure detection. A pair of paths 214B, 214C can be included as a pair of drive components 34, and can include a slot 214A into which the end of the protrusion 174 extends. Paths 214B, 214C may constrain the movement of the protrusion 174 during operation which may help increase the accuracy of the load sensor 98 (FIG. 35B). Accuracy in this context indicates to minimize the deviation of the magnet 158 from the expected path, which can modify the output from the Hall effect sensor 160D and distort the load reading.

The outer portion 173B of the mechanical component 150I can be thickened to prevent distortion of the mechanical component 150I due to runout. The nut 76 of the driven element 60 can be constructed to be used with any of a variety of different projections 92 (FIG. 40). The protrusion 92 (FIG. 40) does not have to be an integral part of the nut 76. The protrusion 92 (FIG. 40) may be attached to the nut 76 using any coupling method, eg, but not limited to, fasteners. The joining method may allow the same nut 76 to be used with any of the plurality of protrusions 92 (FIG. 40). The protrusion 92 (FIG. 40) can include a protrusion body 92D and an interface connection portion 92E.

The linear potentiometer 90B (FIG. 40) may have a wiper 90C (FIG. 40) that can move with or be connected to the nut 76. The wiper 90C (FIG. 40) may move across the resistance element of the potentiometer 90B (FIG. 40) as the nut 76 reciprocates back and forth within the linear needle bearing assemblies 91A, 91B. The linear potentiometer 90B (FIG. 40) may provide feedback on the positions of the nuts 76 and the protrusions 92 as they are displaced by the operation of the motor assembly 70. The positions of the nut 76 and the protrusion 92 (FIG. 40) may be tracked by the number of encoder counters from the motor encoder 90A (FIG. 39). When used in conjunction with the linear potentiometer 90B (FIG. 40), encoder counter tracking provides a level of redundancy and position sensors 90A (FIG. 39) and 90B (FIG. 40) that monitor the movement of the drive element 60. ) Can be collated with feedback data from any of them.

Or it can be a socket.

Still primarily with reference to FIG. 43, the divider 252 can be included inside the trocar 225. The outer conduit 227 of the trocar 225 (FIG. 41) has been removed in FIG. 43 to expose the divider 252. A plurality of dividers 252 may be used in the alternative configuration. The divider 252 can separate the interior of the trocar 225 into several individual lumens, eg, a first lumen 225A and a second lumen 225B, without limitation. Each individual lumen may or may not be fluidly isolated from another lumen, depending on its composition. The divider 252 can have a cross-sectional shape that is selected, for example, to create a desired number of lumens and to define a cross-sectional shape for each lumen. In some configurations, the divider 252 may be "X" shaped and may partially define the first lumen 225A and the opposite lumen (not shown). The divider 252 may also partially define another lumen (not shown) opposite the laterally located second lumen 225B and second lumen 225B. The first lumen 225A and the opposing lumen may have a larger cross section than the second lumen 225B and another laterally located lumen. The lateral lumen may be dedicated to, for example, the operated components 38A, 38B.

Here, with reference to FIG. 44, an enlarged detailed view of one of the driven elements 62A and a part of the manipulator 36D is shown. The side surface 281 of the driven element 62A adjacent to the proximal end 38C of the operated component 38D is molded so that the side surface 281 fits around and adapts to at least a portion of the operated component 38D. Can be done. The driven element 62A can be fitted, for example, into a recess or trough 260 in the manipulator housing 78E. When the manipulator 36D is fully assembled, the driven element 62A can be captured within the manipulator housing 78E. In some configurations, the driven element 62A may be captured between the two manipulator enclosures 78E. Only one manipulator housing 78E is shown in FIG. The receiving structure 250 of the driven element 62A can be aligned with slot 244. The driven element 62A may be displaced within the manipulator 36D. During the displacement, the driven element 62A may be mounted along the bearing. For example, the outer surface 270 of the proximal end 38C of the component 38D to be operated may serve as a bearing for the driven element 62A. The recess or trough 260 in the manipulator housing 78E may also serve as a bearing surface for the driven element 62A. The bearing can constrain the driven element 62A from displacement with undesired degrees of freedom, among other things. In some configurations, the driven element 62A may be mounted along different numbers and / or types of bearings. For example, in some configurations, one of the driven element 62A or the operated component 38D may cooperate with a recessed path in the other of the driven element 62A and the operated component 38D. It may include rails or similar structures that can. In some configurations, the driven element 62A does not have to come into contact with the manipulator housing 78E. Rails or paths may also be included on a portion of the manipulator housing 78E, such as trough 260.

Primarily continuing with reference to FIG. 44, the driven element 62A can include a channel 262 that can reach a mooring point or mooring feature 80. The mooring point 80 can be, for example, but not limited to, a recess or a well. The channel 262 can be cut into the driven element 62 and the mooring feature 80 can be recessed into the top surface of the driven element 62 at a position that can coincide with the cutout 266. The channel 262 can be, for example, but not limited to, located on the same horizontal or vertical plane as the cutout 266. When assembled, the mooring point 80 may be moored to the actuator 54A, which may be a tension wire. Actuator 54A can extend from the well / mooring point 80 through channel 262 into the cutout 266. The actuator 54A can be extended to the length of the operated component 38D until the feature of the operated component 38D operated by the actuator 54A is reached. When the driven component 62A is displaced, the actuator 54A can attract the actuated features of the operated component 38D or return into the operated component 38D to control the operated component 38D. Can be fed as. Such an arrangement can allow relatively simple control of the operated component 38D in that pulling the actuator 54A straight can affect the operation of the operated component 38D. The arrangement can simplify manufacturing and allow the system to operate as expected, which can facilitate processor-assisted control of the operated component 38D. The cutout 266 in the outer surface 270 in the component 38D to be operated may be used as a rail path for the rail 282B (FIG. 46) and the like. When the driven element 62A is displaced within the manipulator 36D, the rail 282B (FIG. 46) may travel and be guided along the length of the wall of the cutout 266.

Still primarily with reference to FIG. 44, the operated component 38D passes through it to various utility components 54 (FIG. 1) such as the actuator 54A, the surgical tool 52 (FIG. 4A), or the auxiliary component 20 (FIG. 1). It can include an outer wall 270, where 4A) can be extended and can demarcate the conduit. The routing insert 272A may be placed within the operated component 38D and may extend along the length of the operated component 38D. The routing insert 272A can abut on the internal surface of the manipulator sheath 38E, leaving a lumen inside the operated component 38D. In other configurations, the routing insert 272A may not be placed within the operated component 38D, but rather may be an integral part of the sheath 38E of the operated component 38D. The routing insert 272A can include at least one routing channel 274 that can provide a route for the actuator 54A. The at least one routing channel 274 can be recessed into the routing insert 272A and is only slightly larger in diameter than the actuator 54A which can extend along the routing channel 274, eg, but not limited to 10-. It can be sized to be 30% larger. Actuator 54A can be a wire or other element that may not have compressive stiffness along its vertical axis. If at least one routing channel 274 is only slightly larger than the actuator 54A, the possibility that the actuator 54A will bundle and become stuck when releasing the slack is if the actuator 54A extends along the routing channel 274. Can be minimized. Desizing at least one routing channel 274, slightly larger than the actuator 54A, allows the actuator 54A to displace without excessive friction, perhaps ensuring smooth and predictable operation. Can be useful for. Actuator 54A may extend along and up to the full length of routing channel 274. The point at which the actuator 54A exits the routing channel 274 may coincide with and be in close proximity to the mooring point 80. Since some pulleys or other routing elements outside the manipulator 36D are not required, the actuator 54A can be constrained within a controlled path to their full length.

Primarily with reference to FIG. 45, the driven element 62D can include a first mooring point 80A and a second mooring point 80B. The mooring points 80A and 80B may each have a separate actuator 54A moored. Actuator 54A can be terminated, for example, with, but not limited to, a crimp or bead 280 that can be sized to fit within one or both of the mooring points 80A, 80B. The crimp or beads 280 may be adhered in place or otherwise adhered. In configurations with two or more actuators 54A attached to the driven element 62D, one material may form, for example, a bridge 263 over channel 262 to the second mooring point 80B. The bridge 263 may be located proximal to the outer surface 270 (FIG. 44) of the operated component 38D (FIG. 44) when the device is fully assembled. The actuator 54A may be fed under the bridge 263 to constrain the actuator 54A so as to exit the operated component 38D (FIG. 44) at a controlled angle. The driven element 62D can be used with a plurality of mooring points 80A, 80B even if the actuator 54A is not moored at the respective mooring points 80A, 80B. Therefore, the same mold can be used to machine the driven element 62D for each side surface of the operated component 38D (FIG. 44). The rails 282A and 282B can extend from the surface 281 of the driven element 62D. The rails 282A and 282B may be mounted in a recessed path into the outer wall or outer surface 270 (FIG. 44) of the component 38D to be operated (FIG. 44). The rails 282A and 282B can be, for example, but not limited to, a dovetail type. Other types of rails 282A and 282B are also possible.

Here, with reference to FIG. 46, a shelf or blade-like rail 282C is shown extending from the surface 281 of the driven element 62E. The shelf-like rail 282C may be mounted in a recessed path within the outer surface 270 (FIG. 44) of the component to be operated 38D (FIG. 44). In some configurations, the shelf-like rail 282C may be mounted within channel 262 in the manipulator 36D (FIG. 44).

Primarily with reference to FIG. 47, the manipulator sheath 38E and the routing insert 272A can include several different routing channels 274A-E. Any one of the routing channels 274A-E or a combination of the routing channels 274A-E can be used. The first routing channel 274A has a first portion 275A recessed into the outer surface 272A of the routing insert 272 and a second portion 275B recessed into the inner surface 270A of the manipulator sheath 38E. Can have. The second routing channel 274B can be located entirely within the wall of the manipulator sheath 38E. In some configurations, the routing insert 272A may be omitted. The third routing channel 274C can be a trough, which can be recessed into the outer surface 272A of the routing insert 272. The fourth routing channel 274D can be a trough that is recessed into the inner surface 270A of the wall of the manipulator sheath 38E. The third routing channel 274C and the fourth routing channel 274D can be, for example, but not limited to, a "U" shape. The fifth routing channel 274E can be located entirely within the routing insert 272A.

Primarily with reference to FIG. 48, the manipulator 36E can include a manipulator housing 78E and some driven elements 62E. The operated components 38A, 38B can each include at least one cutout 266A, 266B, 266C, 266D. The actuator 54A (FIG. 44), such as a wire, may exit through the cutout 266A-D or may be moored to the driven element 62E. The cutouts 266A, 266B, 266C, and 266D can be substantially parallel to each other and can be alternated on different planes. Crop 266A, 266B, 266C, 266D may correspond to the location of at least one routing channel 274 (FIG. 44). The number of cutouts 266A, 266B, 266C, 266D may correspond to the number of driven elements 62E used to operate the operated components 38A, 38B. The cutouts 266A, 266B, 266C, 266D can have substantially the same cutout lengths 267, or the cutout lengths 266A, 266B, 266C, 266D can differ from each other. The cutout length 267 can define the displacement range 63 of each driven element 62E. The exit point of the actuator 54A (FIG. 44) from the cutouts 266A, 266B, 266C, and 266D can change as the driven element 62E is displaced during operation. The cutout length 267 exits the cutout 266A, 266B, 266C, 266D into the driven element 62E at any location along the path of travel or displacement range 63 of the associated driven element 62E. Can be selected so that it can be.

Primarily with reference to FIG. 49, the manipulator 36E, the first drive component 34A, and the second drive component 34B can be aligned for operable engagement. A barrier 24 (FIG. 16), eg, but not limited to, a sterile barrier may be placed between the manipulator 36E and the drive components 34A, 34B. The first manipulator housing portion 78F still accommodates the protrusions of the first protrusion 92A and the second protrusion 92B into the manipulator housing 78, while the ingress of fluid or debris into the manipulator housing 78. Can include an anticline or arch structure 243 that can prevent The second manipulator housing portion 78G may be joined to the first manipulator housing portion 78F so as to complete the manipulator housing 78. The second manipulator housing portion 78G may, for example, have a perforated 230 (FIG. 41) or slotted plateau feature 242 (FIG. 42) to allow the protrusions 92A, 92B of the drive component to enter the manipulator 36E. May include.

Still primarily with reference to FIG. 49, an interface plate 290, such as, but not limited to, a relatively planar rigid element can be adapted to the manipulator 36E and the drive components 34A, 34B. The drive components 34A, 34B may be attached to the interface plate 290 in any suitable manner. The protrusions 92A, 92B can extend through the openings 292A, 292B in the interface plate 290. The interface plate 290 can include several positioning protrusions 294 that can be seated in the recess 236 (FIG. 41) of the manipulator 36E.

Primarily with reference to FIG. 50, when the manipulator 36E is seated on the interface plate 290, the protrusions 92A, 92B extend into the manipulator housing 78 and engage the driven element 62 (FIG. 51). You may. The interface plate 290 may be omitted in some configurations. In configurations without the interface plate 290, the manipulator 36E may be mounted or installed directly on one or more drive components 34A, 34B.

Referring here to FIG. 51, the driven element 62 may be held in a known position within the manipulator 36 to facilitate docking of the manipulator 36 onto the drive component 34 during setup. Known positions may also be referred to as docking positions. Constraining the driven element 62 to the docking position ensures that the drive element 60 is easily pre-aligned for engagement with the driven element 62 in response to the docking of the manipulator 36 to the drive component 34. It can be possible. The drive component 34 may, for example, displace the protrusion 92 to an engagement position that would match the docking position of the driven element 62. When the manipulator 36 is docked onto the drive component 34, the protrusion 92 may engage the driven element 62 as a result of pre-alignment. When the manipulator 36 is docked and the protrusion 92 and the driven element 62 are engaged, the constraint holding the driven element 62 at the docked position may be removed so as not to further interfere with the displacement of the driven element 62. .. Any of a variety of different constraints may be used. The constraint, in some configurations, can contact a portion of the driven element 62 and can prevent the driven element 62 from moving prior to engagement with the driven component 34, mechanical interference. May be. After the manipulator 36 and the drive component 34 are engaged, the constraint may be locked in a retracted or non-interfering position. In some configurations, the displacement of the driven element 62 by the driving component 34 may provide a force to drive the constraint to the retracted position.

Continuing with reference to FIG. 51, the driven element 62 may include a detent 62Z. The detent 62Z may be engaged by the manipulator 36 or the protrusion 78Z included in the manipulator housing 78. In some configurations, the protrusion 78Z can include a ridge 78Y that can be seated in the detent 62Z. When the protrusion 78Z is engaged in the detent 62Z, the protrusion 78Z may hold the driven element 62 in a known or docked position. In some configurations, the protrusion 78Z can be a beam, which can be cantilever-like with respect to a portion of the manipulator housing 78. The protrusion 78Z may be integrally molded with the manipulator housing 78 so that it can extend away from the surface of the manipulator housing 78 and into the detent 62Z. Alternatively, the protrusion 78Z may be urged into the detent 62Z using a bias member such as a torsion spring.

Here, referring to FIG. 52, when the driving element 60 displaces the driven element 62, the protrusion 78Z may be disengaged from the detent 62Z. When the protrusion 78Z is disengaged from the detent 62Z, the protrusion 78Z may be pushed to and retained in a retracted position where it is out of physical contact with the driven element 62. In some configurations, there may be a gap 62Y between the driven element 62 and the manipulator housing 78. When the protrusion 78Z is disengaged from the detent 62Z, the protrusion 78Z and the ridge 78Y do not have to fit in the gap 62Y, and the protrusion 78Z may be pushed to the storage position. The protrusion 78Z may include a flange 78X capable of holding the protrusion 78Z in the retracted position once it is disengaged from the detent 62Z. When the driven element 62 is disengaged from the protrusion 78Z, the flange 78X first abuts on the catch 78W and then bends around the catch 78W to allow the protrusion 78Z to reach the retracted position. You may. In the retracted position, the protrusion 78Z may receive a restoring force capable of pushing the protrusion 78Z towards the driven element 62. The restoring force may be due to the flexure process 78Z trying to return to its original position, or may be the result of a urging member such as a torsion spring (not shown). The flange 78X may be strong enough to receive restoring forces and substantially resist deformation. That is, the flange 78X may be slightly deformed, but may not be deformed to the extent that it bends around the catch 78W.

Primarily with reference to FIG. 53, the hydraulically powered system 1300 can include, but includes, a manipulator 36E, a first drive component 34A, a second drive component 34B, and an interface plate 290. Not limited to that. Barrier 24 (FIG. 17B) can also be included. The drive components 34A and 34B can each communicate with several hydraulic lines 70E. Each hydraulic line 70E can operably communicate with each of the master cylinders 70D, which may be driven by each of the motor assemblies 70. When the piston 70G (FIG. 17B) in the master cylinder 70D is displaced by the operation of the motor assembly 70, the slave piston 70H (FIG. 17B) in the slave cylinder 70F can be displaced, which is the drive component 34A. , The drive element 60 (FIG. 17B) and the driven element 62 (FIG. 17B) in 34B can be displaced. As a result, the operated component 38 can be activated. In some configurations of system 1300, the motor assembly 70 may be remote from the drive components 34A, 34B, which can be made more compact. Further, in some configurations of system 1300, the heat generated by the drive components 34A, 34B can be reduced. The motor assembly 70 and the master cylinder 70D can be located in the remote enclosure 30A, which may be at any suitable location within the surgical system 10 (FIG. 1). The hydraulic line 70E may extend from the remote enclosure 30A to the drive components 34A, 34B. In some configurations, the motor assembly 70 and the master cylinder 70D can be included within the base 30 (FIG. 3) of the surgical robot 16 (FIG. 3), and the hydraulic line 70E is at the arm 32 (FIG. 3). It can extend along or within the arm 32 (FIG. 3).

Here, primarily with reference to FIG. 54, the transmission of force can cause displacement of the component within the second section in several ways, eg, but not limited to, of the component within the first section. It may be done via linear or rotational displacement. In general, the surgical system may employ at least one device with one or more shafts with two ends, such as the operated component 38 (FIG. 16). The first end of the operated component 38 (FIG. 16) may provide one or more end tools or end effectors that may be the surgical tool 52 (FIG. 16). The second end of the manipulator 38 (FIG. 16) is any one or more on the manipulator 38 (FIG. 16) and the first end (either manually or with the help of a processor). It may have a control system and an interface that can be configured to control the end tool 52 (FIG. 16). The first end may be referred to herein as the distal end and the second end may be referred to herein as the proximal end. The manipulator 36 (FIG. 16) may be articulated or maneuverable due to the plurality of joints provided within the manipulator 36 (FIG. 16). The manipulator 36 (FIG. 16) may also serve as a lumen through which the target anatomical site can be accessed. Surgical instrument 52 (FIG. 16) and / or irrigation / blowing fluid may be introduced into patient 18 (FIG. 1) through the main lumen. In addition, or as an alternative, the lumen has one or more utility components 54 (FIG. 16) (eg, light, power, or data transmission components, mechanical control components, fluid conduits, etc., FIG. 4A. See) may be carried. In other configurations, one or more surgical instruments 52 (FIG. 16) may be engaged at the distal end of the manipulator 36 (FIG. 16). In some configurations, the manipulator 38 includes several wire or cable actuators 54A (FIG. 4B) that may be configured to operate an end tool or end effector 52 (FIG. 16) located at the distal end. But it may be. Actuator 54A (FIG. 16) in the manipulator 36 (FIG. 16) may be controlled using electromechanical or electrohydraulic drive systems in various configurations. During the surgical procedure, a portion of the manipulator 36 (FIG. 16) and / or the end tool 52 (FIG. 16) is completely or partially inserted into the anatomical cavity or opening of patient 18 (FIG. 1). May be.

Primarily continuing with reference to FIG. 54, the surgical system 10 (FIG. 1) may include a barrier 24 configured to separate the first compartment of the surgical system 10 (FIG. 1) from the second compartment. However, it is not limited to including it. In some configurations, the barrier 24 serves as a sterile barrier, which may isolate the non-sterile section 513 from the sterile section 515. The location of the sterile barrier 24 may vary depending on the surgical procedure, but the primary purpose may remain the same (ie, isolation of the non-sterile section 513 from the sterile section 515). In some configurations, the barrier 24 may be placed in a location where the disposable portion of the surgical system 10 (FIG. 1) can be attached to the durable portion of the surgical system 10 (FIG. 1). Force may be transmitted across the barrier 24 from the durable portion to the disposable portion so as to control the components within the disposable portion. Non-sterile section 513 may include a durable portion of system 10 (FIG. 1) that can be used for some surgical procedures without requiring a sterilization process such as high pressure steam sterilization. The non-sterile section 513 may include, for example, but is not limited to, components such as electromechanical or electrohydraulic drive components, processing components, other electronic components, user interfaces, and the like. The sterility category 515 may include, for example, but is not limited to, a disposable portion of system 10 (FIG. 1) that may require replacement or sterilization at the end of surgery.

Still further, with reference primarily to FIG. 54, as an alternative, the barrier 24 is such that the actuator 54A (FIG. 16) (which can also be used as a connector) engages the end tool 52 (FIG. 16) or the end tool. It may be placed in a location that can be configured as such. The engagement of the actuator 54A (FIG. 16) and the end tool 52 (FIG. 16) may be provided at one of the first or second ends of the operated component 38 (FIG. 16). In other configurations, the barrier 24 may be placed anywhere towards the distal end of actuator 54A (FIG. 16). The location of the barrier 24 can also be easily sterilized or replaced after any component of the surgical system 10 (FIG. 1) after one or a limited number of uses, and is more difficult to replace and sterilize. It may be selected based on the thing.

Continuing with reference to FIG. 54, the barrier 24 may maintain its integrity as the force is transmitted from the first barrier side surface 24A to the second barrier side surface 24B. In some configurations, the barrier 24 may be, for example, a single continuous blanket, drape, or curtain of material, without limitation. In other configurations, the barrier 24 may be compartmentalized while being functionally equivalent to a single continuous blanket or drape. The barrier 24 may be made of a flexible film, which can be flexible, durable, abrasion resistant, impermeable, and lightweight. In some configurations, the barrier 24 may consist of multiple layers of the same or different materials. Materials that can be used for the barrier 24 can include, but are not limited to, polyurethane. At least a portion of the barrier 24 may contain a coating or material containing an antibacterial agent, and / or the barrier 24 may be provided in a sterile package.

Continuing with reference to FIG. 54, in some configurations, the barrier 24 may not require any adjustment or modification for the transmission of force across it. In some configurations, the barrier 24 may provide one or more pockets capable of accepting and / or covering components on one aspect of the barrier 24. In some configurations, the barrier 24 may be configured to be modified, or may include an integral or attached element to complement and facilitate the transmission of force using a specific mechanism. good. Such modifications may include, but are not limited to, fixing, attaching, or integrally forming the barrier 24 and the element during manufacturing. Such elements may be attached to the barrier 24 in a manner that can maintain the integrity of the barrier 24. That is, after mounting the element, there may be no gaps or other paths within the barrier 24 that provide communication from one side of the barrier 24 to the other. The element may be attached to the barrier 24 in any of a variety of suitable modes. For example, in some configurations, the barrier 24 and at least some of the elements may be made of similar materials that can be ultrasonically welded to each other. The barrier 24 and the element may both be laser welded. The barrier 24 and the element may both be solvent-bonded. The element may be attached to the barrier 24 using an adhesive. The barrier 24 and elements may be formed integrally with each other during manufacturing. In some configurations, the element may be outer coated over the barrier 24. Any other suitable mounting method may also be used. The element may be a built-in cross-linking element that may be surrounded by a flexible membrane or diaphragm. The cross-linking element may be configured to engage one or more components in the non-sterile section 513 and / or one or more components in the sterile section 515.

Continuing primarily with reference to FIG. 54, the sterile section 515 may include an end tool 52 (FIG. 16) or an end effector that may be configured to perform a surgical task during a surgical procedure. In some configurations, the movement of the end tool 52 (FIG. 16) may be controlled by a drive system, which may be operated manually or controlled by or with the help of at least one processor. The first set of components, which may be configured to direct a surgical procedure, may be collectively referred to as the driving element 60. Correspondingly, the second set of components, which may be configured to be automatically driven, manually or automatically assisted, may be referred to as a driven element 62. The driving element 60 may be placed in the sterile section 513 completely or partially, and the driven element 62 may be placed in the sterile section 515 of the surgical system 10 (FIG. 1) completely or partially. You may. In some configurations, the driving element 60 may operate one or more driven elements 62. Alternatively, a single drive element 60 may operate the corresponding driven element 62. The surgical system 10 (FIG. 1) may include a plurality of driving elements 60 and a plurality of associated driven elements 62.

Continuing with reference to FIG. 54, the driven element 60 and the driven element 62 may be arranged to transmit force across the barrier 24 with or without physical contact with the barrier 24. good. In other configurations, the force may be transmitted across the barrier 24 with only one of the driving element 60 and the driven element 62 in contact with the barrier 24. Regardless of how the barrier 24 interacts with the driving element 60 and the driven element 62, the barrier 24 can maintain its integrity as force is transmitted from one side of the barrier 24 to the other. .. Durable components that may be in the non-sterile section 513 may be substantially responsible for directing and controlling aspects of the surgical procedure.

Such an arrangement may be referred to as a contact mode for force transfer. In other configurations, only one of the driven element 60 and the driven element 62 may or may not contact the barrier 24 or the elements within the barrier 24. In an array where neither the driving element 60 nor the driven element 62 touches the barrier 24, the force may be transmitted across the barrier 24 in non-contact mode. Regardless of the mode used for force transmission, the barrier 24 may be at least partially located between the first housing 541 and the second housing 542, or may be held / confined. good.

The second housing 542 may at least partially accommodate the operated component 38 (FIG. 16). In some configurations, the plurality of drive elements 60 and the first barrier interface connection 503 may be arranged within the first housing 541. The plurality of drive elements 60 and the first barrier interface connection 503 in the first housing 541 interact with the plurality of driven elements 62 and the second barrier interface connection 504 in the second housing 542. You may.

Referring here to FIG. 57, the contact arrangement for force transfer may include a manipulator 36E, an interface plate 290, a first drive component 34A, and a second drive component 34B. Not limited to including them. The drive components 34A, 34B may include several drive elements 60 (FIG. 16) that can be operated to displace the protrusions 92A, 92B. In some configurations, the protrusions 92A, 92B may resemble the first barrier interface connection 503 (FIG. 56A). When the manipulator 36E is docked onto the interface plate 290, the protrusions 92A, 92B of the drive components 34A, 34B may act as a second barrier interface connection 504 (FIG. 56A) through the manipulator housing 78. , May extend into the corresponding driven element 62 (FIG. 16). The linear displacement of the protrusions 92A and 92B can cause the linear displacement of the driven element 62. The displacement may actuate the features of the components 38A, 38B to be operated, or may be transmitted down a force carrier such as the actuator 54A (FIG. 16).

Continuing with reference to FIG. 57, the barrier 24 can isolate the manipulator 36E from the drive components 34A, 34B and the interface plate 290. The barrier 24 may be a sterile barrier capable of separating the manipulator 36E on the sterile side surface 515 and the driving components 34A, 34B on the non-sterile side surface 513. The barrier 24 can be captured between the manipulator 36E and the drive components 34A, 34B when the manipulator 36E is docked on the interface plate 290. The barrier 24 may include a pocket-like region 24C for each drive component 34A, 34B. The pocket-like region 24C may be an integral part of the barrier 24, or may be attached to the barrier 24 by any suitable means, such as, but not limited to, solvent bonding, outer coating, and ultrasonic welding. .. The pocket-like region 24C may include several pockets 900 that can be shaped to receive the protrusions 92A, 92B. Each pocket 900 may extend into the manipulator 36E, for example, may project into the receiving structure 250 (FIG. 43) of the driven element 62 (FIG. 16).

Here, primarily with reference to FIG. 58, the barrier 24 is provided to allow for linear displacements of the projections 92A, 92B (FIG. 57) and the displacements resulting from their separate driven elements 62 (FIG. 16). It may include several variable regions that can provide the displacement of the associated pocket 900. The variable region may be made of elastic material, for example, or may be bellows-like. The variable region may be the pleated compartments 24D, 24E of the barrier 24 (FIG. 57). The pleated compartments 24D, 24E may be located on or include the sides of the pocket 900 within the barrier 24, which allows the pocket 900 to be displaced. The amount of displacement may depend on the surface area of the pleats in the pleated compartments 24D, 24E. When the pocket 900 is displaced in a certain direction, the pleated compartment 24D may be folded or compressed, for example, while the pleated compartment 24E allows the pocket 900 to be displaced. It may be flattened.

The pleated compartment 24H can include a plurality of pleats 24I, 24J, 24K. Multiple pleats 24I, 24J, 24K may allow for increased displacement of the pocket 900A. In addition, the plurality of pleats 24I, 24J, 24K can help limit the amount of stress applied to any one of the pleats 24I, 24J, 24K due to the given displacement position of the pocket 900A. The pleated compartment 24H may also include a lateral cusp 24L. The lateral cusp 24L may, for example, project from the pocket 900A in a direction traversing the linear displacement path of the pocket 900A, without limitation. The lateral ridge 24L may help direct the folding and flattening of the pleats 24I, 24J, 24K and may reduce and / or avoid the accumulation or distortion of the pleated portion of the barrier 24.

Here, primarily with reference to FIG. 62A, some configurations of the non-contact torque transfer sequence 660 may include the use of one or more magnetic couplings. The use of magnetic coupling may serve a secondary function of helping to position and secure the first housing 541 (FIG. 56B) to the second housing 542 (FIG. 56B) during setup. In some configurations, the magnetic coupling for the torque transfer array 660 is a magnet on one of the sides 513, 515 (FIG. 56B) and a metal on the other of the sides 513, 515 (FIG. 56B). Materials may be provided. The metallic material may also be a magnetizing material. In configurations with magnetic coupling, one or more magnets may function as the first barrier interface connection 503, and another magnet or group of magnets may function as the second barrier interface connection 504. You may. One or more magnets in each of the barrier interface connections 503, 504 may be aligned with a magnet having opposed poles on the other of the barrier interface connections 503, 504. Any suitable material exhibiting magnetic properties, such as a suitable transition metal, rare earth metal, or alloy, may be used. Neodymium-containing magnets can be used in several configurations, but are not limited to. In some configurations, the type of magnet used in each of the barrier interface connections 503, 504 can be different. The first various magnets or magnetic materials may be included in the first barrier interface connection 503, and the second various magnets or magnetic materials may be included in the second barrier interface connection 504. good.

Primarily continuing with reference to FIG. 62A, the magnetic coupling can transmit torque across the gap 502. The barrier 24 (FIG. 56B) may be placed in the gap 502. The barrier interface connection portions 503 and 504 are respectively arranged at a predetermined distance from the barrier 24 (FIG. 56B) so as to transmit a predetermined force from the first barrier interface connection portion 503 to the second barrier interface connection portion 504. You may. The barrier 24 (FIG. 56B) is placed in the gap 502 so that a portion of the gap 502 on the non-sterile side surface 513 (FIG. 56B) can be substantially equal to that on the sterile side surface 515 (FIG. 56B). You may be aseptic. The force may be transmitted as a result of magnetic attraction and / or repulsion between the poles of one or more magnets constituting each of the barrier interface connections 503, 504. In some configurations, the first barrier interface connection 503 may include, but is not limited to, a set of first magnets or magnetic compartments, the second barrier interface connection 504 may include. A second set of magnets or magnetic compartments may be included, but is not limited to. Barrier interface connections 503, 504 may be aligned so that the poles in the set of first magnets or magnetic compartments can face the opposite poles in the set of second magnets or magnetic compartments. .. Such matching may facilitate torque transfer from the first barrier interface connection 503 to the second barrier interface connection 504. In addition, adjacent magnets or magnetic compartments within each barrier interface connection 503, 504 may be aligned so that their poles are oriented in opposite directions. In other configurations, the first barrier interface connection 503 may include, but is not limited to, a first single continuous magnet, the second barrier interface connection 504 may include a second. It may include, but is not limited to, a continuous magnet of. Still in other configurations, a monolithic piece of material magnetized to include multiple N and S poles (eg, a radial sintered magnetic ring) is the first barrier interface connection 503 and the second barrier. It may be used for each of the interface connection portions 504.

Continued primarily with reference to FIG. 62A, the barrier interface connections 503, 504 may be coupled to one or more force carriers 525,527 on the individual sides of the barrier 24 (FIG. 56B). In some configurations, the force carriers 525 and 527 can be drive shafts. In other configurations, the force carrier 525 disposed on the non-sterile side surface 513 (FIG. 56B) may be included in the drive element 60 (FIG. 16) and may rotate the force carrier 525. The rotation may, in turn, rotate the first barrier interface connection 503. As a result of the magnetic coupling existing between the first barrier interface connection element 503 and the second barrier interface connection element 504, the second barrier interface connection element 504 and the second force carrier 527 are the first barrier. It may rotate in the same manner as the interface connection element 503. Therefore, the magnetic relationship between the barrier interface connecting elements 503, 504 may allow torque to be transmitted across the barrier 24 (FIG. 56B). The movement of the second force carrier 527 may be transmitted to an actuating component such as the surgical tool 52 (FIG. 16).

Primarily with reference to FIG. 62B, the barrier 24 (FIG. 56B) may be placed in the gap 502 during surgery, and the gap 502 may be referred to as the barrier placement gap 502. The gap 502 may be a predetermined distance that is kept substantially constant during operation. The predetermined distance may be chosen so that the barrier 24 may be placed between the barrier interface connections 503, 504, but may not come into contact with any of the barrier interface connections 503, 504. The predetermined distance may be selected so that a desired amount of torque can be transmitted across it. As the predetermined distance is increased, the amount of torque transferred may decrease. In some configurations, the gap 502 may be at a distance of about 0.10 to 0.50 inches. In some configurations, the gap 502 may be about 0.125 to 0.30 inches. The gap 502 may not be symmetrical on either side of the barrier 24. The transmission of force across the gap 502 may occur without any interruption of the barrier 24. As a result, the barrier 24 may function to maintain sterile compartment 515 (FIG. 56B) in isolation from non-sterile compartment 513 (FIG. 56B). The distance of the gap 502 may depend on the various magnetic couplings used.

Although the first barrier interface connection 503 is described primarily with reference to FIG. 62C, the description describes any barrier interface connection 503, 504 that can serve as part of the magnetic coupling (FIG. 62C). 62A) can be applied. The magnets 509A may be arranged to have the opposite polarity to the adjacent magnets 509B. The number of magnets can vary in different configurations. For example, some configurations may include six magnets 509A, 509B in each barrier interface connecting element 503, 504 (FIG. 62A). Each magnet 509A, 509B may be included in a housing 662, which may include a gap 661, where magnets 509A, 509B may be placed during assembly. The housing 662 may be made of any suitable material, including, but not limited to, metal, ceramic, glass, and plastic. In some configurations, the material selected for the housing 662 may be selected, for example, from materials that are compatible for adhesion or ultrasonic welding to the force carrier 525. The housing 662 may also be constructed to affect the magnetic flux paths of the magnets 509A, B in a desired manner. For example, the magnetic flux path may be affected to create one or more closed loop paths. In such a configuration, a portion of the housing 662 (eg, surface 664 (FIG. 62A)) may be made of any metal material capable of creating a magnetic circuit within the barrier interface connection 503. In this configuration, the housing 662 may be constructed such that the magnets 509A, 509B are positioned approximately 180 ° from each other and can be combined together in a magnetic circuit, for example, the magnets 509A, 509B. In the configuration with the three sets of, three magnetic circuits may be created under the influence of the housing 662. For example, the barrier interface connection 503 may be, for example, a force carrier such as, but not limited to, a drive shaft. Receptive feature 666 for 525 can include a receptive feature 666, which can be key-like. In some configurations, the receptive feature 666 has a notch 668 in which the collaborative feature of the force carrier 525 can be seated. In some configurations, the force carrier 525 is notched when fully assembled, for example to ensure that the force carrier 525 and the barrier interface connection 503 do not rotate relative to each other. It may include a ridge 670 that can be accepted in 668.

Referring here to FIG. 63A, the torque transfer array 672 may include one or more force carriers 525, 527, barrier interface connections 503, 504, and barrier 24. The barrier interface connections 503 and 504 may each include one or more magnets and may be magnetically coupled to each other when assembled. The barrier placement gap 502 (FIG. 63B) may be configured to receive the barrier 24 and also allow torque transfer from the non-sterile side surface 513 to the sterile side surface 515. Force transmission may occur without any disruption of the barrier 24 and / or contamination of the sterile side surface 515. As a result, the barrier 24 may function to maintain sterile compartment 515 in a state of being separated from sterile compartment 513.

Here, with reference to FIG. 63B, the first barrier interface connection 503 may provide a first receiving cavity 523 capable of receiving the first force carrier 525. The second barrier interface connection 504 may provide a second receiving cavity 526 capable of receiving the second force carrier 527. Barrier interface connections 503, 504 may also include one or more fastener receiving voids 528, 259 or similar features. Any suitable fastener may be inserted into the fastener receiving voids 528, 259 so as to prevent the rotation of the force of the carriers 525 and 527 with respect to the barrier interface connections 503, 504. In some configurations, different mechanisms may be used to couple the force carriers 525, 527 to the barrier interface connections 503, 504. In some configurations, one or both of the force carriers 525 and 527 may be permanently coupled to the barrier interface connections 503, 504. In such configurations, the components may be welded together (ultrasonically or otherwise), bonded with an adhesive, or solvent-bonded together. In addition, threaded connections or nut and bolt type arrangements may also be used. Any other mechanism that will be apparent to those of skill in the art may be used to couple the barrier interface connections 503, 504 with force carriers 525, 527.

The torque transmission arrangement 520 may be a contact arrangement in which a part of the driving element 60 and a part of the driven element 62 come into contact with the barrier 24. During operation, the barrier 24 may be in physical contact with one or more parts of the driving element 60 and / or physical contact of one or more parts of the driven element 62. The contacted portion of the barrier 24 may be referred to as an engaging portion. Contact through the engagement site may allow the transmission of torque from the driving element 60 in the non-sterile section 513 to the driven element 62 in the sterile section 515. The second barrier interface connection 504 may be configured to receive the transmitted torque and pass it to an actuated feature such as the end tool 52 (FIG. 16) to facilitate the surgical task. In some configurations, the barrier 24 may not undergo any modification or adjustment. The force is confined in such a state that at least a part of the barrier 24 is physically contacted and confined between one or more parts of the driving element 60 and one or more parts of the driven element 62. It may be transferred from the first barrier side surface 24A to the second barrier side surface 24B. In other configurations, the barrier 24 provides a receptacle or receptor for receiving one or more portions from the non-sterile side surface 513 and / or one or more portions from the sterile side surface 515. Adjustments or modifications, such as, but not limited to, may be configured. In other configurations, a cross-linking element or a plurality of cross-linking elements may be provided as part of the barrier 24. The cross-linking element may be configured to engage a portion of the driving element 60 and / or a portion of the driven element 62.

Continuing with reference to FIG. 64A, the reference shaft 535 may serve as a rotating shaft around which the driven element 60 and the driven element 62 can rotate. The barrier 24 may be displaced when torque is transmitted from the drive element 60 to the driven element 62. Specifically, when the torque is transferred, nutation "fluctuations" occur and the torque is transferred without requiring the barrier 24 to rotate and without the need for a rotary seal within the barrier 24. Can make it possible. The displacement of the barrier 24 can be explained for several different reference axes, such as a second reference axis or tilt axis 539. The second reference axis 539 may be perpendicular to the barrier surfaces 24A, 24B. The barrier 24 may be held between the first barrier interface connecting element 503 and the second barrier interface connecting element 504 so that the angle O can be formed between the reference axis 535 and the tilting axis 539. good. The angle O may be maintained when torque is transmitted from the first barrier side surface 24A to the second barrier side surface 24B. The tilt axis 539 is, for example, the first
The nutation may be centered on the reference axis 535 according to the nutation path 537 of. The tilt axis 539 may also maintain an orientation substantially perpendicular to the first barrier side surface 24A and the second barrier side surface 24B. The dotted line indicator 538 indicates the position of the tilt axis 539 and the barrier 24 after about 180 ° rotation of the drive element 60 and the driven element 62 about the reference axis 535. The barrier angle α between the first surface 24A of the barrier 24 and the reference axis 535 can also be substantially constant during torque transmission across the barrier 24.

Continuing with reference to FIG. 64B here, nutations can also be explained for various other axes. For example, a third reference shaft or barrier nutation shaft 541 may be used to account for the displacement of the barrier 24 as torque is transmitted through the torque transfer array 520. The barrier nutation axis 541 may be substantially perpendicular to the reference axis 535 and may be arranged to intersect the reference axis 535 at the point where the barrier 24 intersects the reference axis 535. The barrier nutation axis 541 may also be referred to as the barrier nutation axis 541. The barrier nutation axis 541 may form an angle β with the barrier 24. The torque transmitted from the first barrier interface connection portion 503 to the second barrier interface connection 504 forms at least a part of the barrier side surfaces 24A and 24B centering on the barrier nutation axis 541 according to the second nutation path 536. You may move it. The dotted contour 501A indicates the position of the barrier 24 after rotation of the driving element 60 and the driven element 62 about 180 ° around the reference axis 535. If the barrier 24 is displaced while torque is being transmitted, the angle β may remain substantially constant.

Referring here to FIGS. 64C-64F, the barrier 24 is displaced as the driving element 60 (FIG. 64B) and the driven element 62 (FIG. 64B) rotate about the reference axis 535. Specifically, advances in FIGS. 64C-64F illustrate the nutation "fluctuation" of the barrier 24 as torque is transmitted from the first barrier side surface 24A to the second barrier side surface 24B. The nutation "fluctuation" of the barrier 24 can be of any scale and is not limited by any of the illustrated configurations herein. In some configurations, only a small section of the barrier 24 at and around the engagement site may be displaced. The displacements of the drive rotation indicators A, B, C, and D corresponding to the individual driven rotation indicators A', B', C', and D'represent the rotation of the driving element 60 and the driven element 62. In FIG. 64C, the torque transfer array 520 is in the initial position. The driving element 60 (FIG. 64B) and the driven element 62 (FIG. 64B) in each of FIGS. 64C-64F are displaced by about 90 ° rotation from their position in each of the aforementioned figures. Torque can be transmitted across the barrier 24 by the rotational displacement of the drive element 60 (FIG. 64B). Reference marking 674 on the barrier 24 indicates that torque is transmitted without the barrier 24 need to rotate and without the need for a rotation seal within the barrier 24. In addition, the nutation displacement of the barrier 24 may facilitate torque transfer without any distortion or effect on the integrity of the barrier 24.

Referring here to FIGS. 65A-65D, the torque transfer sequence 530 can transfer torque from the non-sterile side surface 513 of the barrier 24 to the sterile side surface 515 in contact mode. Specifically referring to FIG. 65A, the torque transfer sequence 530 may include a plurality of components on the non-sterile side surface 513 that cooperate with the plurality of associative components on the sterile side surface 515. The components on the non-sterile side surface 513 may be included in the first barrier interface connecting element 503. The associative component on the sterile side surface 515 may be included in the second barrier interface connecting element 504. The first barrier interface connecting element 503 includes, for example, but is not limited to, a first force carrier 555, a first planar body 543, a first cap base 551, and a first engaging cap 547. But it may be. The second barrier interface connecting element 504 may include a second engaging cap 549, a second cap base 553, a second planar body 545, and a second force carrier 557. In some configurations, the first and second force carriers 555, 557 may be torque transfer agents (eg, drive shafts). The first and second force carriers 555, 557 may be coupled to the planar body 543, 545 so that the force carriers 555, 557 and the planar body 543, 545 cannot rotate relative to each other. Welding of any suitable bonding method, such as, but not limited to, threaded joints, fasteners (eg, positioning screws), clamps, snap fits, adhesives / glues / epoxys, ultrasonic or laser welds, etc. Procedures, solvent gluing, spring-loaded bayonet mounts, and others may be used. Alternatively, each set of force carriers 555, 557, planar body 543, 545, and cap bases 551, 552 may be formed as a single part that can be machined or molded, for example, depending on the configuration.

Primarily continuing with reference to FIG. 65A, at least a portion of the barrier 24 that separates the sterile side surface 513 from the non-sterile side surface 513 may be captured between the caps 547 and 549. The first barrier interface connection cap 547 and the second barrier interface connection cap 549 may contact the barrier 24 when assembled and engage or lock with each other through the barrier 24. Rotation of the barrier interface connections 503, 504 around the reference axis 535 can cause displacement of the barrier 24. The barrier 24 may be displaced in a manner that allows the tilting axis 539 to be nutated about the reference axis 535. The tilt axis 539 may form an angle O (FIG. 64A) with the reference axis 535, and this angle may be maintained as the tilt axis 539 nutates. In addition, the first barrier interface connection cap 547 and the second barrier interface connection cap 549 are trapped in the barrier 24 while the barrier interface connection portions 503 and 504 are rotating about the reference axis 535. The barrier 24 may be confined to maintain the portion at an angle α (FIG. 64A) with respect to the reference axis 535. The first force carrier 555 may be configured to receive torque from a torque generator (eg, a motor) and transmit the torque to the first planar body 543. The first planar body 543 may further include a base 551 that extends from the first planar body 543 and may have a surface 551A at an angle 551B with respect to the reference axis 535. The surface 551A may serve as a mounting platform or platform for the first bearing assembly 565 (FIG. 65C) housed within the end cap 547. The first bearing assembly 565 (FIG. 65C) may allow rotational displacement of the end cap 547 with respect to the base 551. In some configurations, the end cap 547 may provide the outer surface of the bearing assembly 565 (FIG. 65C).

Continuing primarily with reference to FIG. 65A, the sterile side surface 515 may provide a collaborative component that may be configured to receive torque transmitted from the non-sterile side surface 513. These components may be collectively referred to as the barrier interface connection 504 and may be included in the driven element 62 (FIG. 64B). These components may be similar to or the same as those on the non-sterile side 513 of the barrier 24. For example, the driven barrier interface connection 504 may include a second bearing assembly 567 (FIG. 65C) that may be encapsulated in a second cap 49, which may be referred to as a second barrier interface connection cap 549. The second bearing assembly 567 (FIG. 65C) may allow rotational displacement of the second end cap 549 with respect to the second base 553. The second barrier interface connection cap 549 and the housed bearing 567 (FIG. 65C) may be mounted on the second base 553. The second base 553 may include a surface 551D that is oriented at an angle 551C with respect to the reference axis 535 and may extend from the second planar body 545. The second flat body 545 may be attached to, for example, but not limited to, a second force carrier 557 such as a drive shaft. The second force carrier 557 may be configured to receive the transmitted torque and advance it to an actuated component such as the end effector 52 (FIG. 16). In addition, the barrier interface connection caps 547 and 549 may be placed on separate bases 551 and 553 such that the respective faces of the end caps 547 and 549 may be perpendicular to the tilt axis 539. During torque transmission, the torque transmission array 530 may be configured to rotate about a reference shaft 535. The operation of the torque transfer array 530 may, for example, cause, but is not limited to, the response nutation movement of the barrier 24. Torque may be transmitted without the need for rotation of the barrier 24, rotation seals within the barrier 24, or discontinuities (eg, holes) within the barrier 24. The torque transfer sequence 530 may allow the faces of the end caps 547 and 549 to remain perpendicular to the tilt axis 539 during the transfer of torque from the non-sterile side surface 513 to the sterile side surface 515.

Referring here to FIG. 65B, the end caps 547 and 549 may include co-engagement or interlocking features. For example, one of the end caps 547 and 549 may include a grooved recess or recess 546. The other of the end caps 547 and 549 may include a raised feature 548 that can mesh into the grooved recess 546. Such engagement of 547 and 549 may help maintain engagement of the end caps 547 and 549 during torque transfer through the torque transfer array 530. In some configurations, the grooved recess 546 can be included in the surface 580 and the raised feature 548 can be included in the surface 581 (FIG. 65D). Surfaces 580, 581 (FIG. 65D) can engage the barrier 24 during operation. The grooved feature 546 may partially or completely occupy the surface of the end caps 547 and 549. In some configurations, the grooved feature 546 can be an annular feature that can be located in the vicinity of the perimeter of the end caps 547, 549, but is not limited to. The raised feature 548 may partially or completely occupy the surface of the end caps 547 and 549. In some configurations, the raised feature 548 may be located in the vicinity of the perimeter of the end caps 547, 549, but may be an annular feature. Grooved recesses 546 and raised features 548, as well as end caps 547 and 549, may have smooth, rounded or rounded edges. In some configurations, the grooved recess 546 and the raised feature 548 and the end caps 547 and 549 may be made from or coated with a soft flexible material or a material with a low coefficient of friction. In other configurations, the co-engagement or mutual locking features can be different. The barrier 24 may be confined between the end caps 547 and 549 when the torque transfer array 530 is engaged with the barrier 24. The site where the barrier 24 can be confined can be referred to as the engagement site 563. Any engaging member may be included on the barrier interface connections 503, 504 instead, in addition to the end caps 547, 549. The alternative engaging member is smooth and may have rounded edges. The engaging member may also be made of, or coated with, a soft flexible material or a material with a low coefficient of friction.

Here, with reference to FIG. 65C, a cross-sectional view of the torque transfer array 530 shown in FIG. 65A is depicted. The barrier 24 can be trapped or held between the end cap 547 on the sterile side surface 513 and the end cap 549 on the sterile side surface 515. The first bearing assembly 565 may be provided on the non-sterile side surface 513 and the second bearing assembly 567 may be provided on the sterile side surface 515. The first cap base 551 and the second cap base 553 may provide a first support column 570 and a second support column 571. The support columns 570 and 571 may project from the surface of the cap bases 551 and 553. The first support column 570 may abut on the inner guide groove of the first bearing assembly 565. The second support column 571 may abut on the inner guide groove of the second bearing assembly 567. The first bearing assembly 565 may promote low friction displacement of the end cap 547 with respect to the cap base 551 and the support column 570. Similarly, the second bearing assembly 567 may promote low frictional displacement of the end cap 549 with respect to the cap base 553 and support column 571. Bearing assemblies 565 and 547 may be selected to support predetermined axial and moment loads on the aseptic side surface 513 and sterile side surface 515, respectively. In some configurations, the bearing assembly 565 and 567 may be, but is not limited to, a roll element bearing assembly such as a ball bearing assembly or a needle bearing assembly. In some configurations, angular contact bearings may be used.

Here, with reference to FIG. 65D, the barrier 24 can be confined between the first barrier interface cap 547 and the second barrier interface cap 549. As the first barrier interface connection 503 and the second barrier interface connection 504 approach the barrier 24, the grooved recess 546 and the raised feature 548 hold the barrier 24 interconnected and held between them. It is also good. The end caps 547 and 549 may remain engaged and the barrier 24 may remain confined between the end caps 547 and 549 during torque transfer.

Referring now to FIG. 65E, the first barrier interface connection 503 (FIG. 65C) of the torque transfer array 530 (FIG. 65C) is a single continuous structure that can be machined or molded together as a single component. A possible planar body 543 and base 551 can be included. The components of the second barrier interface connection 504 (FIG. 65C) may be similar to, may be the same as, or different from those of the first barrier interface connection 503 (FIG. 65C).

Here, with reference to FIGS. 65F and 65G, additional configurations related to the mutual locking features of the end caps 547 and 549 are shown. FIG. 65F depicts a grooved feature 546 arranged radially on the surface 580 of the end cap 547. Also included is a collaborative radial arrangement of raised features 548 on surface 581 of the opposed end cap 549. Note that the grooved features 546 and raised features 548 can be interchangeably arranged on the faces 580, 581 of the end caps 547 and 549. During operation, the end caps 547 and 549 of the torque transfer array 530A may come into contact with the barrier 24. The radial groove features 546 and the radially arranged raised features 548 may be locked together through the barrier 24. This may help prevent rotation of one of the end caps 547 and 549 relative to the other. Like other configurations, the radially arranged grooved and raised features 546 and 548 may have rounded edges and may be coated with a flexible and / or low coefficient of friction material. And so on. The radially arranged grooved and raised features 546 and 548 may, but are not limited to, be spaced evenly spaced apart.

Here, with reference to FIG. 65G, another configuration of the mutual locking feature between the faces 580 and 581 of the end caps 547 and 549 is shown. FIG. 65G shows an asymmetric distribution of grooved features 546 and raised features 548 on the end caps 547 and 549 planes. The dimples or receptacles form a grooved feature 546 on the face 580 of the end cap 547. There is a collaborative asymmetric distribution of ridge features 548 on the surface 580 of the end cap 549. The ridge feature 548 may be a protrusion or protrusion that projects high from the surface 581. Note that the grooved features 546 and raised features 548 can be interchangeably arranged on the faces 580, 581 of the end caps 547 and 549. During operation, the end caps 547 and 549 of the torque transfer array 530B may come into contact with the barrier 24. The raised feature 548 may sit in the groove feature 546 and lock the end caps 547 and 549 together through the barrier 24. This may help prevent rotation of one of the end caps 547 and 549 relative to the other. Like other configurations, the grooved and raised features 546 and 548 may have rounded edges, may be coated with a flexible and / or low coefficient of friction material, and the like. Grooved and raised features 546 and 548 are shown as being asymmetrically placed around cap surfaces 580, 581 in other configurations, but they are symmetrically spaced, for example, at even angular intervals. It may, but is not limited to. In some configurations, such as any of those shown in FIGS. 65A-G, the end caps 547 and 549 may be magnets or may include them. In addition to the mechanical interlocking provided by the grooved and raised features 546 and 548, magnetic coupling may also be formed. This may further assist in preventing relative rotation of one of the end caps 547 and 549 with respect to the other. In addition, magnetic coupling can help position the end caps together when setting the torque transfer array 530B. The magnetic coupling between the two end caps 546 and 548 can also help confine the barrier 24 between the two end caps 546 and 548.

Referring here to FIG. 66A, the barrier 24 may include at least one element, eg, a cross-linking element 600 that can interact with, but is not limited to, a portion of the driven element 60 and the driven element 62. The cross-linking element 600 can be configured to connect the components on the non-sterile side surface 513 of the torque transfer sequence 573 to those on the sterile side surface 515. The torque transfer sequence 573 may be isolated on the non-sterile side surface 513 and the sterile side surface 515 using the barrier 24. The driving element 60 can be positioned on the non-sterile side surface 513 and the driven element 62 can be positioned on the sterile side surface 515.

The cross-linking element 600 is partially or completely fixed onto the barrier 24 so that the cross-linking element 600A may be accessible on the non-sterile side surface 513 and the cross-linking element 600B may be accessible on the sterile side surface 515. May be done. In some configurations, the cross-linking element 600 may be a rod or pin-like member, and the accessible portion of the cross-linking element 600 on each side of the barrier 24 may be coaxial. In some configurations, the first barrier interface connection 503 is configured to receive a first receptor 625, eg, an accessible portion of a bridging element 600 on a non-sterile side surface 513, such as, but not limited to. , Pockets or ports may be provided. Similarly, the second barrier interface connection 504 on the sterile side surface 515 also receives a second receptor 630, eg, but not limited to, an accessible portion of the cross-linking element 600 on the sterile side surface 515. A pocket or port may be provided. In other configurations, the bridging element 600 may include, but is not limited to, a restraint structure, a permanent fastener, and a screw coupling, which may be coupled on both sides using alternative means. If the cross-linking element 600 is configured to be a metal, eg, but not limited to, a metal pin, the magnetic components on either or both sides of the barrier 24 are the first and second receptors 625, It may be included as part of 630.

Continuing with reference to FIG. 66A, in some configurations, a plurality of cross-linking elements 600 may be provided on the barrier 24. The plurality of cross-linking elements 600 may allow the plurality of pairs of barrier interface connecting elements 503, 504 to engage in force transfer across the barrier 24. In some configurations, the cross-linking element 600 may be branched or split. Such an array may also allow, for example, one of the driving elements 60 to drive a plurality of driven elements 62. The cross-linking element 600 may facilitate torque transmission across the barrier 24. The cross-linking element 600 may be secured within the barrier 24 so that it cannot receive rotational movement with respect to the barrier 24. The tilt axis 539 may be arranged perpendicular to the barrier side surfaces 24A and 24B of the barrier 24. In some configurations, the vertical axis of the bridging element 600 may be coaxial with the tilt axis 539. In some configurations, the cross-linking element 600 can be placed perpendicular to the barrier 24. Nutation movements may occur as torque is transmitted. For example, the cross-linking element axis may be nutated about the reference axis 535 as the barrier interface connections 503, 504 rotate about the reference axis 535. The angle between the bridging element 600 and the barrier 24 with respect to the reference axis 535 may remain constant as torque is transmitted through the torque transfer assembly 573.

Continuing with reference to FIG. 66A, the cross-linking element 600 may be anchored within the barrier 24 using any of the various processes. The cross-linking element 600 may be attached to, for example, but not limited to, an adhesive to the barrier 24 or may be molded as part of the barrier 24. In some configurations, the crosslinking element 600 may be ultrasonically welded, laser welded, thermally bonded, or solvent bonded to the barrier 24. The cross-linking element 600 may be made of various materials. For example, the cross-linking element 600 may be made of a metallic material. Alternatively, the cross-linking element 600 may be made of a plastic material or fiber reinforced plastic, eg, but not limited to, glass fiber. The material choice for the cross-linking element 600 may depend on the amount of force expected to be transferred through the cross-linking element 600. In some configurations, the cross-linking element 600 may be constructed from or coated with a material with a low coefficient of friction.

Referring here to FIG. 66B, in some configurations, the cross-linking element 600 may optionally include or be attached to a flexible diaphragm 605. The flexible diaphragm 605 may include an orifice of predetermined dimensions. The orifice is a cross-linking element such that the first branch or portion 600A of the cross-linking element 600 may be accessible on the sterile side surface 513 and the second branch or portion 600B may be accessible on the sterile side surface 5153. It may be configured to accept 600. The flexible diaphragm 605 may be configured to be integrally formed with the barrier 24, and the cross-linking element 600 may later be attached to the flexible diaphragm 605 after a location in the orifice. Alternatively, the flexible diaphragm 605 may be attached to the cross-linking element 600 and may be outer coated, for example, without limitation. In some configurations, the flexible diaphragm 605 may assist in the attachment of the cross-linking element 600 to the barrier 24. When attached to the barrier 24, the flexible diaphragm 605 and the barrier 24 may form a seal from which the environment on each aspect of the barrier 24 can be isolated. The material used for the flexible diaphragm 605 may include polyurethane, or any other suitable material that is flexible, durable and may be inert to the metal. Not limited to include. The flexible diaphragm 605 may be made of, for example, a material with properties that facilitate ultrasonic welding, laser welding, and solvent adhesion to the barrier 24, without limitation. For example, in configurations where the barrier 24 is a polyurethane material, the flexible diaphragm 605 may also be constructed from polyurethane to facilitate ultrasonic welding of the flexible diaphragm 605 to the barrier 24.

Here, primarily with reference to FIG. 67A, the torque transfer assembly 5580 can include a barrier 24 with a cross-linking element 600. The cross-linking element 600 may be partially or completely anchored to the barrier 24. In some configurations, the cross-linking element 600 can be secured to the barrier 24 at the attachment site 603. The mode of mounting at the mounting site 603 can prevent rotational displacement of the bridging element 600 with respect to the barrier 24. The first component or portion 600A of the cross-linking element 600 may be accessible on the non-sterile side surface 513 and the second component or portion 600B of the cross-linking element 600 may be accessible on the sterile side surface 515. The first portion 600A of the cross-linking element 600 may be received by a receiving structure 611, which may be part of a barrier interface connecting element 503 that can be included in the driving element 60 (FIG. 66A). The receiving structure 611 may be disposed on the non-sterile side surface 513 of the barrier 24 or may be configured to interface to the barrier 24 via a first portion 600A of the cross-linking element 600. The second portion 600B of the cross-linking element 600 may be accepted by the second receiving structure 613. The second receiving structure 613 may be disposed on the sterile side surface 515 of the torque transfer sequence 5580. In some configurations, the second receiving structure 613 may be configured to serve as a barrier interface connection 504 on the sterile side surface 515 and is included as part of the driven element 62 (FIG. 66A). It may be. To facilitate the transmission of torque, the first receiving structure 611 and the second receiving structure 613 may rotate about a reference axis 535. The transmitted torque across the barrier 24 may be received by the multi-pocket receptor 613A via the cross-linking element 600. The torque supplied to the second receiving structure 613 may, for example, cause rotation of the end tool 52 (FIG. 16). When the first receiving structure 611 rotates about the reference axis 535 and the torque is transmitted to the second receiving structure 613, the long axis 600C of the cross-linking element 600 can nutate around the reference axis 535.

Here, referring to FIG. 67B, the barrier 24 can include a flexible diaphragm 605. The first receiving structure 611 may include a receiving pocket 612, which may be configured to receive the first portion 600A of the cross-linking element 600. In some configurations, the receiving pocket 612 can be defined by an inner guide groove in the bearing assembly 610. The presence of the bearing assembly 610 can allow low friction rotation of the first receiving structure 611 with respect to the first portion 600A of the bridging element 600 during operation. In some configurations, the bearing assembly 610 can be, for example, but not limited to, a needle bearing assembly. Roller bearings such as ball bearings may also be used. Alternatively, the first receiving structure 611 may include a receiving pocket 612 without rolling bearing elements. In some configurations, the walls of the cross-linking element 600 and / or pocket 612 may be made or coated with a material with a low coefficient of friction. In some configurations, the first receiving structure 611 may be made from a strong and durable material such as a metallic material.

Still referring to FIG. 67B, the second receptor structure 613 may be a multi-pocket-like receptor that can include several individual receptor pockets 615. The second receiving structure 613 may be made of a material containing various types of rigid plastics, but not limited to. A plastic having a low coefficient of friction when interfaced with the cross-linking element 600 material may be selected. In some configurations, the second receptive structure 613 may be made from a material such as, but not limited to, surgical grade stainless steel that is resistant to degradation after repeated sterility. The pockets 615 of the second receiving structure 613 may be sized and shaped to receive the second portion 600B of the cross-linking element 600, respectively. The pocket 615 may also be contoured to guide a second portion 600B of the cross-linking element 600 into the pocket 615. The inclusion of the plurality of pockets 615 in the second receptive structure 613 may allow for increased ease of configuration as the second receptive structure 613 does not need to be precisely oriented at a specific position. Alternatively, the second receiving structure 613 may be positioned in various rotational orientations and may be readily meshable with the second portion 600B of the cross-linking element 600. The first receiving structure 611 may include a plurality of receiving pockets 615 in some configurations to reduce any setting burden. The bearing assembly 610 may also be included in the second receiving structure 613 in some configurations.

Here, with reference to FIGS. 67C and 67D, two cross-sectional views of the torque transfer array 5580 are shown. FIG. 67C is an assembly drawing, while FIG. 67D is an exploded view.

Referring here to FIG. 67C, the first receiving structure 611 can engage the first portion 600A of the cross-linking element 600, and the second receiving structure 613 is of its plurality of receiving pockets 615. In one, it can engage the second portion 600B of the cross-linking element 600. The first receiving structure 611 may be configured to engage the driving element 60 (FIG. 56A). Torque may be supplied to the drive element 60 (FIG. 66A) and transmitted to the first receiving structure 611. The engagement between the drive element 60 (FIG. 66A) and the first receiving structure 611 is, for example, using a keyed shaft such as a splined shaft that can be received in the first receptacle 616, without limitation. And may be established. The first receiving structure 611 may further provide a bearing assembly 610 configured to be disposed within a recess or cavity 633 within the first receiving structure 611. In some configurations, the bearing assembly 610 may be, but is not limited to, a needle bearing or an angular contact needle bearing. The torque supplied to the first receiving structure 611 may be advanced to the second receiving structure 613 (having the second receptacle 617) using the cross-linking element 600. The second receiving structure 613 may pass the received torque through the driven element 62 (FIG. 56A) to an actuated feature such as the surgical tool 52 (FIG. 16).

Here with reference to FIG. 67E, the ratio of the length of the first portion 600A of the cross-linking element 600 to the second portion 600B of the cross-linking element 600 may be modified to modify the amount of torque transferred. .. By increasing the length of the first portion 600A relative to the second portion 600B, a larger amount of torque may be transferred from the first side surface 24A to the second side surface 24B. Shortening the first portion 600A of the cross-linking element 600 relative to the second portion 600B can have the opposite effect. In some configurations, the first portion 600A can be longer than the second portion 600B and can have, for example, a length ratio of about 2: 1.

Here, referring to FIG. 67F, modifying the angle 600D of the major axis 640 of the bridge element 600 with respect to the reference axis 535 may modify the amount of torque transmitted. Keeping the length of the first portion 600A and the second portion 600B of the cross-linking element 600 constant, the amount of torque transmitted may increase as the angle 600D of the major axis 640 with respect to the reference axis 535 increases. .. In some configurations, the angle 600D can be, for example, 55-60 °.

Referring here to FIG. 67G, other modifications may also be made to modify the amount of torque transmitted. For example, in some configurations, one of the first portion 600A or the second portion 600B of the cross-linking element 600 may include an extending arm 641. The extending arm 641 may be attached to the end of the cross-linking element 600. The extending arm 641 may extend from the bridging element 600 at an angle that allows the extending arm 641 to extend away from the reference axis 535 and be substantially perpendicular to it. Placing the extending arm 641 on the driving side of the cross-linking element 600, eg, the non-sterile side 513, may increase the amount of torque transmitted. Placing the extending arm 641 on a driven side surface, eg, a sterile side surface 515, may reduce the amount of torque transmitted.

Referring here to FIG. 68, in some configurations, the gear train 676 may be included as part of the driven element 62. The gear train 676 may couple the force carrier 678 attached to the second barrier interface connection 504 to the drive shaft 680. The drive shaft 680 may control the actuated features such as the end tool 52 (FIG. 16) either directly or indirectly. The gear train 676 may be employed to reduce the repulsion perceived during operation. Without the gear train 676, the drive element 60 may rotate at a first speed. The rotational speed of the drive element 60 may be increased in the same manner as the gear deceleration in order to reduce the repulsion perceived by the gear train 676. The gear of the gear train 676 may be a repulsion prevention gear. In some configurations, gear train 676 may be included with 10: 1 gear deceleration. If the drive element 60 is driven tenfold at the first speed, the perceived repulsion can be reduced by about 90% (remove any repulsion in the gear train 676). Instead of gear deceleration, the gear train 676 may instead be a mechanical amplifier, used as an amplifier to increase torque. Any suitable gear ratio may be selected to amplify the torque by the desired amount.

Here, referring to FIG. 69, the manipulator 36E may be seated on the interface plate 290. The drive component 34A may be operated to cause displacement of the driven element 62 (FIG. 68) within the manipulator 36E. This may in turn activate the end tool 52 above one of the features and / or the manipulated components 38A, 38B of the manipulated components 38A, 38B. The uppermost portion 78A of the manipulator housing 78 is disassembled to depict the inner components of the manipulator 38E. The rotational drive component 34C may transmit torque to the component within the manipulator 36E, the component to be operated 38A, 38B, or the end tool 52. For example, the rotation of the barrier interface connection portion 503 of the rotation drive component 34C may rotate the end tool 52. The barrier interface connection 503 may be, but is not limited to, any of those described herein. The barrier interface connection 503 may be adjacent to the end 78V of the manipulator 36E. The barrier interface connection 503 may be positioned to transmit torque to a second barrier interface connection 504 in the manipulator 36E at or near the end 78V of the manipulator 38E. The barrier interface connection 504 may be, but is not limited to, any of those described herein.

Continuing with reference to FIG. 69, in some configurations, the rotary drive component 34C may be covered by a rotary drive component cover or housing 290A. In some configurations, the rotational drive component housing 290A may be part of an interface plate 290 that rises above the plane of the interface plate 290. The rotary drive component enclosure 290A may allow the drive component 34A and the rotary drive component 34C associated with the manipulator 36E to be under the interface plate 290. In some configurations, all rotational drive components 34C for the manipulator 36E may be covered by the rotational drive component enclosure 290A. In some configurations, the manipulator 36E can have a "V" shaped enclosure 78. In such a configuration, the rotational motion transmitted from the rotational drive component 34C to the second barrier interface connection 504 may need to be passed around the bend 78U. A general purpose joint (not shown) may be included in the rotating portion (eg, a force carrier such as a force carrier 527 (FIG. 56B)) to facilitate the main transmission of rotational motion around the bent portion. The manipulator 36E does not have to be "V" shaped and may instead be constructed to avoid having to transmit any rotational motion around the bend 78U.

Referring here to FIG. 70, the manipulator 36E positioned for docking on the interface plate 290 may include a barrier 24. The barrier 24 may include a rotational drive component cover or shroud 24M in addition to the pocket-like region 24C. The rotation drive component cover 24M of the barrier 24 may be sized so as to surround the rotation drive component housing 290A or the rotation drive component 34C. In addition, when the manipulator 36E is docked on the interface plate 290, the shroud 24M may extend between the rotational drive component housing 290A and the end 78V of the manipulator housing 78. The first barrier interface connection 503 (FIG. 69) and the second barrier interface connection 504 (FIG. 69) are provided with a portion of the barrier 24 between the rotational drive component housing 290 and the end of the manipulator housing 78. Torque may be transmitted between them. The barrier 24 may maintain isolation of the manipulator 36E from the drive components 34A, 34C. In some configurations, elements within the barrier 24, such as the cross-linking element 600 (FIG. 66A), may extend into the rotational drive component housing 290A and / or the end 78V of the manipulator 36E. Similarly, in some configurations, a portion of the first barrier interface connection 503 (FIG. 69) or the second barrier interface connection 504 (FIG. 69) is removed from the rotational drive component enclosure 290A, respectively. Alternatively, it may extend outward from the end 78V of the manipulator 36E.

Primarily with reference to FIG. 71, at least a portion of the operated component 38 may be articulated to facilitate the use of the operated component 38 to perform surgery on patient 18 (FIG. 1). .. The joint movement may involve moving or displacing the operated component 38 or a portion of the operated component 38 in any of several degrees of freedom. Moving or displacing the operated component 38 may be accomplished by displacing the actuator 54A (FIG. 4B) connected to the articulated compartment 40 (FIG. 4B) of the operated component 38. The operated component 38 can extend from the manipulator 36 and, for example, can bend away from the neutral axis 400. The neutral axis 400 can be aligned with the vertical axis of the operated component 38 when the operated component 38 is not activated or is in the "home" position. The degree to which the operated component 38 is bent away from the neutral axis 400 can be referred to as a bending angle Θ _b 403.

Here, referring to FIG. 72, the bending plane 402 or the plane on which the operated component 38 can be bent may be modified. The bending plane 402 may rotate about the neutral axis 400. The amount by which the bending plane 402 is rotated from the reference plane 404 can be expressed as the rotation angle Θ _r 405. In a configuration in which the articulated compartment 40 (FIG. 4B) is controlled by the actuator 54A (FIG. 4B), the articulated compartment 40 (FIG. 4B) is configured by displacing the actuator 54A (FIG. 4B) in a controlled manner. It can be operated to the desired position. For any combination of rotation angle Θ _r 405 and bending angle Θ _b 403 (FIG. 71), the amount of displacement of actuator 54A (FIG. 4B) can be determined. Drive component 34 (FIG. 71) attaches actuator 54A (FIG. 4B) in a determined amount required to achieve the commanded angle of rotation Θ _r 405 and bending angle Θ _b 403 (FIG. 71). It can be instructed to displace. Therefore, the operated component 38 may be articulated to the desired orientation or configuration. The angle of rotation Θ _r 405 and / or the angle of flexion Θ _b 403 (FIG. 71) may be defined manually or automatically. For example, the user is any suitable user interface or input, such as, but not limited to, a joystick, roller ball, jog wheel, knob, touch screen, or other user input device 14 (FIG. 1) as described herein. Using the structure, the angle of rotation Θ _r 405 and / or the angle of bending Θ _b 403 (FIG. 71) can be entered.

Primarily with reference to FIG. 73, the operated component 38 can include a joint motion type compartment 40. The control of the configuration with the three actuators 54A (FIG. 8) described herein can be extended to include any number of actuators 54A (FIG. 8). The operated component 38 can include a variable portion 39 and a joint movement type compartment or portion 40. The variable portion 39 can be stretched and articulated. The operated component 38 can be fully articulated or can include a variable articulated unit. The variable portion 39 can be located proximal to the manipulator 36 and the articulated compartment 40 can be located distal to the manipulator 36. The variable portion 39 can be, for example, but not limited to, rigid or unjoined. The articulated compartment 40 can have a neutral or home position and can be flexed at a flexion angle Θ _b 403 (FIG. 74). The articulated compartment 40 can start from the starting plane 408. For reference, two points 412, 414 on the operated component 38 located on the starting plane 408 are shown. The nominal length 43, represented by "L", is the length of the articulated compartment 40 when the articulated compartment 40 is aligned in the home or neutral position along the neutral axis 400.

Primarily with reference to FIG. 74, points 412 and 414 may remain stationary during the joint movement of the joint movement type compartment 40. Points on the articulated compartment 40 distal to the starting plane 408 may move during articulation. A first movable point 420 and a second movable point 418 at the distal end of the joint movement type division 40 are also shown for reference. In some configurations, the plane 408, the first quiescent point 412, and the second quiescent point 414 move in response to user interaction with the robot 16 (FIG. 1) of the surgical system (FIG. 1). You may. In some configurations, the first quiescent point 412 and the second quiescent point 414 are translated as the operated component 38 is moved back and forth (eg, stretched in or out). It may be displaced. In some configurations, there may be more than one articulated compartment 40 in the manipulated component 38. In such a configuration, the starting plane 408 for one of the articulated compartments 40 may move as the other of the articulated compartments 40 is articulated. As the plane 408 moves, all points on the operated component 38 distal to the plane 408 may also move in the same manner. The nominal length 43 may be arc length in some configurations when the articulated compartment 40 is not in the neutral or home position (shown in FIG. 73). In some configurations, when not in the home position, the nominal length 43 is equal to the length of the arc between the second quiescent point 414 and the second movable point 418 for a given bending angle Θ _b 403. obtain. The nominal length 43 can be substantially constant regardless of the bending angle Θ _b 403.

With reference primarily to FIG. 74, the desired length L _des of the actuators 54A, 54B (eg, cable or wire) with respect to the bending angle Θ _b 403 can be determined. The desired length L _des can correspond to the length of the actuator 54A located within the bending plane 402 (FIG. 72) (when the angle of rotation Θ _r 405 (FIG. 72) is 0 °). The term "cable length" is used herein to refer to the length of portions of actuators 54A, 54B within the articulated compartment 40. When the articulated section 40 is displaced from its home or neutral position (FIG. 73), the cable length is generally arc length. The arc 421 between the first movable point 420 and the first stationary point 412 represents the actuator 54A with the length of L _des for the exemplary bending angle 403 shown. The total actuator length can be substantially longer than the cable lengths of the actuators 54A, B in the articulated portion 40. For example, the actuators 54A and 54B in many configurations can extend not only along the joint motion type division 40 but also along the variable portion 39. Actuators 54A, 54B can also exit from the operated component 38 so that they can be moored to the driven element 62 (FIG. 16).

Primarily continuing with reference to FIG. 74, offset 419 of actuators 54A, 54B from the neutral axis 400 can be used to determine L _des . Offset 419 is represented herein by "Ω". For example, considering the bending angle Θ _b 403, L _des is the length of the arc 421 between the first movable point 420 and the first stationary point 412 with respect to the actuator 54A straddling between the points 420 and 412. Can be equal to. L _des can be determined using the following relationship.

r-Ω = L _des / Θ _b
In the equation, r is equal to L / Θ _b or the radius defining the nominal length L43 for a given bending angle Θ _b 402 in radians. L / Θ _b can be assigned to r and the relationship can be reorganized as follows.

LL _des = Ω * Θb = _Δlength

Since the nominal length L43, the offset Ω419, and the bending angle Θ _b 403 can be grasped, the L _dess may be calculated. _Δlength is the difference between L and L _dess . The _Δlength value is to calculate the desired length of any number of actuators 54A, 54B that may be present in the articulated compartment 40 to achieve a flexion angle Θ _b 403 and a rotation angle Θ _r 405. May be used for. The configuration of one method for doing so is described herein.

Mainly referring to FIG. 75, the operated component 38 can include, for example, a first actuator 54A, a second actuator 54B, and a third actuator 54C. The desired lengths of the first actuator 54A, the second actuator 54B, and the third actuator 54C can be identified as L _{des1, L des2, and L des3 , respectively} . The distance between the point 426 on the neutral axis 400 (FIG. 74) and the actuators 54A, 54B, 54C can be referred to as cable offsets 419A, 419B, 419C, respectively. In the configuration where the bending plane 402 (FIG. 72) is fixed or the angle of rotation Θ _r 405 is zero, L _{des 1} can be calculated as follows.

_Δlength ^* cos0

The first actuator 54A, the second actuator 54B, and the third actuator 54C can each be, for example, but not limited to, angle offset from each other by 120 °. All angular offsets may be defined in connection with one of the actuators 54A, 54B, 54C, eg, the actuator 54A. The first angle offset 427A, represented herein as "Θ _offset2 ," is the angle between the first actuator 54A and the second actuator 54B. The second angle offset 427B, represented herein as " _Θoffset3 ," is the angle between the first actuator 54A and the third actuator 54C. Illustratively, Θ _offset2 is 120 ° and Θ _offset3 is −120 °. Therefore, L des2 = _Δlength ^* cos (Θ _offset2 ) and L _des3 = _Δlength ^* cos (Θ _{offset3 )} . When Θ _r 405 (Fig. 72) ≠ 0, L des1 = _Δlength ^* cos (0 + Θ _r ), L _{des2 = Δlength *} ^cos (Θ _offset2 + Θ _r ), and L _des3 = _Δlength ^* cos ( _{Θ ).} + Θ _r ). If the articulated compartment 40 includes an additional actuator (not shown in FIG. 75), the desired length of the additional actuator can be calculated in the same general fashion. These lengths are used to calculate the required amount of displacement to move the articulated compartment 40 to the desired flexion angle Θ _b 403 (FIG. 74) and rotation angle Θ _r 405 (FIG. 72). You may. The desired bending angle Θ _b 403 and the desired angle of rotation Θ _r 405 may be specified either manually (eg, by the user) or automatically. After the desired length of the actuators 54A, 54B, 54C has been determined, the desired length may be compared to the current length of each of the actuators 54A, 54B, 54C. The calculated difference between the desired actuator length and the current actuator length may be referred to as the length error. These length errors may be expressed, for example, as length _err1 , _{longth err2} , and _longth err3 of the first actuator 54A, the second actuator 54B, and the third actuator 54C, respectively. The length error value may be used to instruct drive component 34 (FIG. 71) to cause displacement of actuators 54A, 54B, 54C. When the actuators 54A, 54B, 54C are displaced, the operated component 38 displaces the actuators 54A, 54B, 54C so that the length error value is zero, thereby causing a desired bending angle Θ _b 403 (FIG. 71). ) And the angle of rotation Θ _r 405 (FIG. 72).

Primarily continuing with reference to FIG. 75, the desired bending angle Θ _b 403 (FIG. 71) can be recorded over time to define a set of motions that can be reproduced later. For example, the exercise of a skilled operator can be recorded to provide a program for use by the trainee, or the operator's own exercise is required by the operator during a procedure or other procedure. It can be recorded to reduce the number of repetitive exercises.

Primarily with reference to FIG. 76, for example, method 450 for controlling the movement of a joint movement type compartment 40 (FIG. 74) having three wires is a step of receiving at least one command signal by a robotic surgical system. 431 can be included, but is not limited to. The at least one command signal may be, for example, but is not limited to, may be provided by the user input device 14 (FIG. 2) or may be a representation of a user-instructed move command. In some configurations, the one or more sensors associated with the user input device 14 (FIG. 1) may output a representation of the move command directed by at least one user. The sensor output may represent the amount of displacement of a portion of the user input device 14 (FIG. 1), the location of the user's finger on the touch screen, and the like. Method 450 can include 432 steps to filter at least one command signal. The command signal may be filtered in some configurations, including, for example, dead zones. Gain may also be applied to the command signal. Method 450 can include step 433 to determine the desired angle of rotation Θ _r and bending angle Θ _b , at least in part, based on the command signal. Method 450 can also include, for example, but not limited to, step 435 of determining the _Δlength value as described herein. Method 450 can include, for example, but not limited to, step 437 of calculating the respective length _des value of the actuator based on the _Δlength value as described herein. Method 450 can also include step 439, which calculates the respective Length _err value of the actuator based on the Length _des value, and step 441, which generates a displacement command based on the Length _err value. Method 450 can optionally include a step of filtering the lens _err value and displacement command. Method 450 can further include step 443 of transmitting displacement commands to various motor assemblies (eg, in drive component 34 (FIG. 71)). The command may be addressed to a particular motor within the drive component 34 (FIG. 71) that can control the movement of the specific actuator. The drive component 34 (FIG. 71) of the robot 16 (FIG. 3) may drive the actuator until the controller 15 (FIG. 1) determines that the respective legth _err value of the actuator is equal to zero. Encoder counts, potentiometers, other displacement sensors, or combinations of displacement sensors may be used to determine the length of each wire or actuator.

Continuing with reference to FIG. 76, in some configurations it is desirable that the controller 15 (FIG. 1) be programmed to control the joint movements of the operated component 38 (FIG. 75) in a plurality of different modes. obtain. These modes may be user-selected or may be automatically populated based on data collected from sensors in the robot 16 (FIG. 3). For example, the controller 15 (FIG. 1) may have a macroscopic movement mode and a fine adjustment mode. The processing of the command signal received in step 431 may differ in each of the plurality of modes. In various configurations, each mode is defined by a number of configurable parameters or a set of configurable parameters that can determine how the command signal will be handled by the controller 15 (FIG. 1). It can be possible. For example, the speed at which the lens _err value of each actuator is zeroed may depend on the mode selected. The percentage may be a parameter that can vary for each of the modes. The speed may be user-definable in some configurations. In other configurations, the desired angle of rotation Θ _r and bending angle Θ _b as determined from a given user input may vary depending on the mode selected. The desired angle of rotation Θ _r and bending angle Θ _b may receive gains that can increase or decrease these values. This gain may be a specifiable parameter for each mode.

Still further with reference to FIG. 76, using the macroscopic and micromoving mode embodiments, the macroscopic movement mode is a rapid and / or rapid and / or rapid movement type portion of the operated component 38 (FIG. 75). Will allow for large displacement movements. This mode may be used, for example, to move the operated component 38 (FIG. 75) within the surgical site, the end effector 52 (FIG. 16) on the operated component 38 (FIG. 16). It can be useful in putting it in the general place needed to perform surgery. The fine movement mode will allow small and precise movement of the articulated portion 40 (FIG. 74) of the operated component 38 (FIG. 75). This mode may be used in a confined space or during surgical procedures such as cutting, suturing, and cauterization. In some configurations, the functionality associated with some or all surgical procedures may be disabled when the system is not in micro-movement mode. For example, the operation of the end effector 52 (FIG. 16) on the robot 16 (FIG. 3) may be disabled. Continuing to refer to macroscopic and micromotor movements, the desired angle of rotation Θ _r and bending angle Θ _b may be scaled up or down depending on the mode in which the controller 15 (FIG. 1) is operating. In addition, or as an alternative, the speed at which the length _err value of each actuator is zeroed can vary. For example, in the macroscopic movement mode, the lens _err value of each actuator can be set to zero relatively quickly, while this speed can be relatively slow in the micro movement mode.

Referring here to FIGS. 76A, 76B, and 76C, the controller 15 (FIG. 3) determines an actuator in the cable 76A14 from the start position 76A3 to the desired position 76A2 by determining the respective neutral length 76A4 of the actuator 76A32. The length of each of the 76A32 can be determined. The controller 15 (FIG. 3) divides the actuator 76A32 into linear lengths 76C3 (FIG. 76C) and multiplies the number of linear lengths forming the actuator by the size of the linear length 76C3 (FIG. 76C) to obtain a neutral length 76A4. It can be determined. The controller 15 (FIG. 3) can determine the pitch angle 76B1 (FIG. 76B) as the angle between the tensioned length 76A5 and the projection 76B4 (FIG. 76B) onto the horizontal axis 76B3 (FIG. 76B). .. The controller 15 (FIG. 3) can determine the yaw angle 76B2 as the angle between the horizontal axis 76B3 (FIG. 76B) and the projection 76B4 (FIG. 76B). The controller 15 (FIG. 3) can calculate the rotation angle 76C1 (FIG. 76C) as atan (sin (pitch angle) / sin (yaw angle)). The controller 15 (FIG. 3) bends as an intersection 76A8 between the projection from the first end 76A3 of the actuator drawn at the angle of rotation 76C1 (FIG. 76C) and the projection 76A10 of the second end of the actuator. The bending radius 76A7 as the arc 76A6 and the neutral length 76A4 / bending arc 76A6 can be determined. The controller 15 (FIG. 3) may determine the cable offset 76A12 as the distance between the actuator 76A4 and, for example, but not limited to, the center 76A13 of the cable 76A14 capable of accommodating four of the actuators 76A4. can. The controller 15 (FIG. 3) can determine the actuator angle 76A30 as, for example, an acute angle between the actuator 76A12 and the Cartesian shaft 76A31 drawn in the cable 76A14. In some configurations, the controller 15 (FIG. 3) can calculate the length of each actuator as a neutral length 76A4 + bending arc 76A6 ^* cable offset 76A12 ^* sin (rotation angle 76C1 + actuator angle 76A30).

Here, primarily referring to FIG. 77, a method 475 for applying tension to an actuator for a surgical robot is a drive component such that tension is applied to a first actuator until a force in the load path reaches a predetermined threshold. Can include, but is not limited to, include step 451 instructing. The force may be determined, for example, by sensing the displacement of a flexible member such as the mechanical component 150 (FIG. 26) located in the load path, without limitation. At 453, if the force value has not reached the threshold, method 475 can include repeating step 453 to monitor the force value. At 453, if the force value has reached a predetermined threshold, method 475 can include step 455 identifying another actuator to apply tension. In some configurations, the actuator may be tensioned in a cross-tension sequence or pattern. In configurations that use cross-tension, the actuator finds an actuator that acts on the feature of component 38 to be operated (FIG. 75), which is substantially the opposite of the feature controlled by the pre-tensioned actuator. Can be identified in step 455. The actuator will therefore be tensioned in a cross-cross fashion similar to the tightening of an ear nut on a wheel. As a result, when the actuator is tensioned, the articulated parts of the operated component can remain substantially in the same orientation or position throughout the process. Spiral sequences may also be used if the actuators are arranged in a non-circular pattern. In the alternative configuration, the application of tension can be preprogrammed in the desired sequence and no processor determination of the actuator is required.

Still referring to FIG. 77, method 475 can further include step 457 of applying tension to the identified actuator until a force in the identified actuator load path exceeds a predetermined threshold. If the force in the load path has not reached a predetermined threshold at 459, method 475 may include repeating step 459 for monitoring force. If the force in the load path reaches a predetermined threshold at 459, and if there is an additional actuator that applies tension at 461, method 475 can include step 455 that identifies another actuator that applies tension. .. When all of the actuators are tightened to their individual thresholds, additional steps of tensioning may be preformed. In such a configuration, the actuator may be incremented to the desired final tension value in one or more increments. If the force in the load path has reached a predetermined threshold at 459, and if there is no additional actuator to apply tension at 461, and if there is an additional tensioning step at 463, method 475 will probably be It can include step 465 of adapting a predetermined threshold to the next predetermined threshold, and step 451 of repeating the step of applying tension to the first actuator, for example by sending a command to the motor. At 463, if there is no step of applying additional tension, method 475 can be terminated.

Continuing with reference to FIG. 77, for example, the first step of applying tension may apply tension to the actuator up to a quarter of the desired final tension value, the second step may be the desired final tension value. Tension may be applied to the actuator up to half of the above, and so on. The number of stages of applying tension can vary depending on the configuration. In addition, the increment for each step can vary depending on the configuration. All of the actuators may be tensioned in equal increments at each stage of tensioning, or the actuators may be assigned individual tension increments for each stage. The stiffness of the operated component 38 (FIG. 75) can be varied to best suit the surgical needs, as the tension on each of the actuators can be controlled to the desired amount. Variable stiffness can allow some tools 52 (eg, retractors) or tools to be more rigid, while other tools (eg, shavers or cauters) are more flexible. Can be. Variable stiffness can be useful in controlling the amount of bounce that can occur in a given tool if the force across the axis of the operated component 38 (FIG. 75) is suddenly removed. Forces across the axis can occur when obstacles are encountered and overcome. For example, when cutting through the target tissue, the force across the axis will no longer be present when the cut is complete. By reducing the actuator tension (making the operated component 38 (FIG. 75) more flexible), the resulting bounce can be diminished. In some configurations, the cable tension on the actuator can be, for example, but not limited to, up to 80 pounds.

Still further with reference to FIG. 77, the ability to vary stiffness may enable dynamic stiffness control. The stiffness of the operated component 38 (FIG. 75) may be modified in situ to suit a given situation. In some configurations, the operated component 38 (FIG. 75) has a default stiffness setting that is active when the operated component 38 (FIG. 75) is introduced into the patient 18 (FIG. 1). be able to. The default settings may specify tension, which can allow the tool to be substantially flexible. The default settings can be general settings or tool-specific. When preferred, stiffness alters the flexibility of the operated component 38 (FIG. 75) when the tool is performing a surgical mission such as cutting, separating, or holding tissue in place. It may be modified to make it. The stiffness of the operated component 38 (FIG. 75) may be set or changed in various ways. In some configurations, the controller 15 (FIG. 1) can be configured to control the operated component 38 (FIG. 75) in a plurality of modes. Rigidity may be a definable parameter for each of the multiple modes. The mode can be selected automatically or manually with the desired stiffness for the component 38 to be operated (FIG. 75). In configurations that include macroscopic and micromoving modes, the stiffness settings for each mode can be different. The macroscopic movement mode may be assigned default stiffness, for example, while the micro movement mode may be more rigid or less rigid.

Claims

Referring here to FIG. 28E, the manner in which the deformable body 152G can be distorted can also be influenced by the shape of the deformable body 152G. In some configurations, the deformable body 152G may be coupled or mounted on a component of the drive system that may be displaced due to the runout of a portion of the drive system. To mitigate any effects of runout, or to allow for more generous runout tolerances, the mechanical component 150F is due to any rotation around the secondary axis, or any of the drive shafts. It may be constructed to have a low tendency to displace as a result of other rotational eccentricities. The deformable body 152G can include several thinned spans 162 that can be defined by channels 164 that are recessed or cut out through the deformable body 152G. The outer portion 163 of the deformable body 152G is relatively thick and can serve as a buttress against distortion due to runout. The outer portion 163 of the deformable body 152G may also serve to accommodate the threaded insert 166A (FIG. 28D). At least one side surface of the deformable body 152G can include a gap 168. The form and arrangement of the deformable body 152G and the channels 164 and the thinned span 162 may be selected to make the deformable body 152G elastic against undesired distortions. In some configurations, the morphology of the deformable body 152G and the arrangement of the channels 164 and the thinned span 162 can make the deformable body 152G generally behave as several four-bar connections. Such a parallelogram frame configuration may reinforce the deformable body 152G against undesired deformation. Additional channels 164 and thinned compartments 162 may be added to increase the amount of distortion caused by a given load. The mechanical component 150F can also include a stop surface 166. When the deformable body 152G is pressured and distorted, the gap 168 between the stop surface 166 and the rest of the deformable body 152G can be reduced until contact is made with the stop surface 166. The stop surface 166 can limit or prevent distortion of the deformable body 152G when the load on the deformable body 152G reaches a desired amount. The mechanical component 152G can, for example, respond to a first range of loads rather than a second range of loads, without limitation. The stop surface 166 may be replaced or replenished with the threaded insert 166A (FIG. 28D). In configurations that include a flag or protrusion 154, the protrusion 154 may be sized to produce the desired amount of amplification of the distortion of the deformable body 152G. When a load 156 (FIG. 28D) is present, the displacement of a point above a portion of the most distal protrusion 154 of the deformable body 152G is the protrusion multiplied by the radian angle of the protrusion 154 with respect to its no-load position. Will be approximately equal to the length of. The longer protrusion 154 may be used to generate further amplification.
